A swim bottom that digs in, rides up, or gaps at the back can ruin a whole beach day. Side-tie and drawstring designs let you tighten or loosen the fit on the sand, so you are not locked into one size. This guide breaks down seven adjustable bikini bottoms with the fit notes, coverage details, and fabric facts that matter when you buy swimwear online.

Swimwear is hard to buy without trying on, and a tie you can tighten or loosen yourself changes that. The picks below span body types and budgets, so you can find the right adjustable bikini bottoms without guessing.
Our Picks at a Glance
How To Choose The Best Adjustable Bikini Bottoms
The biggest reason a swim bottom ends up in a drawer is a fit that will not budge. Adjustable ties solve half of that problem; the cut and the fabric solve the other half. Here is what to weigh before you buy.
Why the side tie matters more than the size on the tag
A side tie is a knot on each hip that lets you loosen or tighten the bottom by hand. That flexibility means an in-between size is not a dealbreaker — you can cinch a medium down or let a large sit comfortably. What you want to check is whether the strings are long enough to tie securely and short enough not to dangle awkwardly.
Coverage: full seat versus cheeky
Coverage describes how much of your backside the fabric actually covers. A full-coverage cut keeps everything contained, while a cheeky cut leaves more exposed. Many adjustable bottoms sit somewhere in the middle, so read the description closely if you want a specific amount of coverage rather than guessing from the photo.
Lining and fabric opacity
Lining is a second layer of fabric sewn inside the front panel. A lined bottom stays opaque when wet; an unlined one can turn sheer once it hits the water. If you plan to swim rather than just sunbathe, lining is not optional — it is the difference between a suit you trust and one you keep tugging at.

In‑Depth Reviews
1. Daci Women’s Side Tie Mid Rise Bikini Bottom
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
The mid-rise side-tie that holds everything in without looking like shapewear.
This is the pick that gets the fundamentals right for the widest range of bodies. The fit is where it wins people over — it is the single attribute owners bring up most, far ahead of anything else. The side ties let you tighten or loosen the hips on the fly, and the mid rise sits between a low cut and a high waist, which is the range most people find comfortable for a full day on the sand.
The drawstring detail on the sides is what makes the fit feel custom rather than fixed. Reviewers describe it as true to size, snug through the midsection with tummy control, and comfortably full through the rear with just a slight cheeky cut. One buyer summed up the experience plainly: full coverage without looking granny-ish. It also matches well with tops you may already own, which makes it an easy one to pair.
Here is the trade-off worth knowing. A few people note the rise reads a touch higher than the mid-rise label suggests, so if you want a clearly low-cut bottom this is not it. The tummy control also means a snugger feel through the middle than a plain string tie. Neither is a defect — just know that the fit is on the supportive side rather than the relaxed side.
What earns the top spot
- Side ties give real adjustability on the hip
- Mid rise with tummy control that stays snug
- Full rear coverage with a slight cheeky cut
- Soft, well-made fabric that holds up
Where it asks a little
- Rise can read higher than “mid” suggests
- Supportive fit, not a loose string-tie feel
- Fuller coverage may be more than some want
Grab it if: you want one reliable bottom that tightens over the hips and flatters the midsection.
Think twice if: you specifically want a low-cut or skimpy string bottom.
2. Women’s Swim Bottom Tie Side Bikini Bottom Tankini Swimsuit Briefs
A low-rise tie-side that sits down on the hip and covers the front fully.
If you like your bottoms to sit low on the hips, this cut is built for that. The quality is the strength owners call out most, and it holds a clean, fitted look without the frills of a print or bead. The design mirrors the listing photos closely, so what you see is what arrives. The side ties give you a knotted adjustment, and the low rise keeps the whole thing feeling relaxed rather than held-in.
Unlike the Daci pick above, this one is a low-rise cut rather than a mid rise, so it rests lower on the hip and the seat coverage is on the cheekier side. The front coverage stays full and opaque, which matters for how confident you feel stepping out of the water. At this value tier it is one of the more affordable ways to get a genuinely adjustable tie-side bottom without stepping into the premium range.
The thing to plan around is sizing. The fit runs inconsistently — some find it true to size while others say it comes up large, and a few mention baggy spots that persist no matter how tight you tie the strings. Sizing is the trade-off here. If you are between sizes, sizing down tends to serve most people better with this cut.
Fabric and feel: a soft, comfortable material that matches the listing shot, with ties long enough to knot securely and short enough not to look messy.
Honest caveat: the sizing is the one variable to watch, so measure before you commit if you are near a size boundary.
Reach for this if: you want a low-rise, budget-friendly tie that covers the front well.
Look elsewhere if: you need a mid or high rise, or a consistent true-to-size fit.
3. La Blanca Women’s Side Tie Hipster Bikini Bottom
The hipster with a print and bead detail that reads dressier than the price.
What sets this one apart is the look. The fit and fabric quality are the two things owners praise most, and the spice-market print with bead accents gives it a polish the plainer ties do not have. The fabric feels substantial and the pattern stays vivid. It is fully lined and not see-through, so it holds up as a swim bottom rather than just a photo-ready one.
The side ties let you adjust between sizes, which is exactly where they earn their keep. The coverage is full through the back, and the low tummy keeps the front flattering without cutting in. Style-wise it mixes and matches easily with tops in complementary colors and patterns, so it works as part of a set you build yourself.
Two things to know. The cut runs a little large and a little high for some, and adjusting the ties can create a small gap at the front on certain body shapes. As with the recommendation to size down elsewhere, the practical move here is often to take your usual size or one below rather than trusting a chart that may push you up. The bead accents are a nice touch but worth a gentle hand wash to keep them looking sharp.
Standout detail: a substantial, fully lined fabric with a vivid print and bead accents that survives the water.
The catch: it runs slightly large and slightly high, and tie adjustments can gap at the front, so fit is the one thing to dial in.
Suits you if: you want a flattering, fully lined hipster with real print character and adjustable ties.
Skip the guesswork if: you prefer plain solids or need a guaranteed low-cut rise.
4. Tempt Me Women Bikini Bottoms Side Tie Adjustable Bathing Suit Bottom
A mid-rise that smooths the middle and stays put through a real swim.
The mid rise and full coverage here are the whole point. Owners call out the fit and the coverage as the two best things about it, and the fabric has a thickness that reads substantial rather than flimsy. The adjustable side-tie string lets you set how high it sits and how much coverage you want, and the tummy-control construction smooths the abdomen without feeling restrictive — which makes it a popular pick for postpartum wearers who want support without a high-waist cut.
It holds up to real use too. Buyers report washing it by machine and hanging it to dry, and taking it through chlorine, salt water, and fresh water without the shape giving out. The side ties let you scrunch the look as much or as little as you like. That combination — supportive midsection, full seat, and durable fabric — is why it sits among the stronger performers in this group.
Two caveats come up. Sizing runs small, and some people need to go a full size up to get the right fit. A few also mention the color fading over time with heavy pool use. Neither undermines the fit-and-coverage strength that most buyers praise — they are just the two details to plan around, especially if you swim in chlorinated water often.
Where it shines: a mid rise with tummy control, full coverage, and an adjustable tie that stays in place while you move.
Size up note: the fit runs small, so a comfortable size may be one above your usual.
Your pick if: you want smoothing midsection support with full coverage and a tie you can tighten mid-swim.
Not the one if: you prefer low-rise or strictly true-to-size ordering.
5. Zmart Women’s Side Tie Bikini Bottoms Full Coverage Bathing Suit
A high-cut mid-waist bottom that lengthens the leg and still covers fully.
The balance here is unusual: a leg-lengthening high cut paired with full coverage, held together by adjustable side ties. Fit is the quality owners rave about most, and the material is thick enough to feel secure without being heavy. The mid waist sits comfortably in the middle of the range, and the ties give a tailored fit that stays put through pool and ocean use — a buyer who lives in Hawaii reports it holds through water sports without the strings coming undone.
What makes it versatile is how it reads on different bodies. Buyers across a range of ages and sizes describe it as flattering without looking bulky, and one notes the cut works well for those with a fuller seat who usually fight a gap at the back. It comes in multiple colorways, and the fabric handles cold wash and hang dry without issue. It is a solid everyday choice if you want the high-cut leg look without giving up coverage.
The catch is fit consistency. The coverage and quality land well for most, but the cut runs a bit loose on some bodies, and a rare buyer finds the bottom too big. There is also the honest note that this one mostly gets pool-tested rather than surviving heavy wave action. If your body shape runs toward the slimmer end, tie the sides snugly and check the rise before committing.
The winning combination
- High-cut leg that reads lengthening, not skimpy
- Adjustable side ties that stay tied through water sports
- Full coverage without bulk, across body types
- Substantial fabric that survives cold wash and hang dry
Worth knowing
- Runs a bit loose on some body types
- Mostly pool-tested rather than wave-tested
- Cut may need a snugger tie for slimmer frames
A strong fit for: anyone who wants the high-cut leg look with full coverage and a tie that survives the water.
Pause if: your frame runs slim and you want a guaranteed snug starting fit.
6. String Tie Side Full Coverage Bikini Bottoms Mid Rise Swim Bottom
A mid-rise string tie whose sides feel secure instead of risky.
Side ties on cheap bottoms have a reputation for coming loose, but this one earns trust. The fit is the aspect owners praise most, and the most frequent compliment is that the ties feel secure and keep everything where it belongs. The mid rise keeps the front at a comfortable height, and the string construction lets you pull the coverage to where you want it. The material is thick rather than flimsy, and it holds its color through washing.
Where it differs from the fuller-cut picks above is the amount of fabric. This reads as a genuine string bottom, so it is cheekier through the back than the Daci or Tempt Me options — the front cut is good, but the rear is slightly more exposed. If a string-bottom silhouette is what you are after, that is a feature rather than a flaw.
The honest limit is durability and cut. A few mention the front rise sits a touch low, and there is a rare report of the material feeling less substantial over time after washing, so gentle handling helps. It is worth sizing up if you want a little more comfort, and sizing down if you want the snuggest fit the ties allow. The takeaway is simple: secure ties, true mid-rise front, and a rear that runs cheeky.
Best thing about it: ties that feel genuinely secure, so you are not constantly re-knotting them poolside.
Keep in mind: the rear runs cheeky and the front sits low, so it is not the fullest-coverage option here.
Buy it when: you want a true string tie that holds tight and stays put around the pool.
Keep looking if: you need maximum rear coverage or a higher front rise.
7. CUPSHE Women’s String Bikini Bottom Side Tie Cheeky Swim Bottom
The cheeky string tie that flatters over the belly and stays where you tie it.
This is the premium option, and quality is where it earns its place at the top of the range. Owners point to fabric quality as the strongest attribute, with the fit close behind. The cut covers the lower belly without riding too high, which is the balance a lot of cheeky bottoms miss. Adjustable side ties give a tailored fit, and the recommended size tends to land accurately, so ordering your usual size is a reasonable starting point.
The details separate it from the budget string ties. The straps carry a small silver bead accent that buyers find cute, and the material is soft and breathable without leaving marks. Buyers also note it does not roll down, and it ties tight and stays tied once you set the knot — which is the daily frustration most string bottoms create and this one avoids. Colors arrive true to the listing photos.
Two things to weigh. The ties run long, and some buyers trim them and readjust the beads to get a cleaner look. There is also a note about longer shipping times. Neither touches the fit-and-quality strength that puts it at the top of this group — they are simply the practical details to expect when you order.
Premium edge: soft, breathable fabric with a lower-belly-covering cut that stays tied and does not roll down.
Minor snag: the ties arrive long and may need trimming, and shipping can take longer than expected.
This is your pick if: you want a premium cheeky string tie with accurate sizing and fabric that stays tied all day.
Look elsewhere if: you want full rear coverage or a mid or high rise.
Understanding the Specs
Rise: low, mid, and high
Rise describes where the top edge of the bottom sits on your torso. A low rise sits down on the hip, a mid rise sits between the hip and the waist, and a high rise climbs toward or above the waist. Higher rises cover more of the midsection, which is why tummy-control cuts usually combine a mid or high rise with a firmer fabric. Pick the rise based on how much of your torso you want covered, not on the size number.
Coverage and the cheeky cut
Coverage is the amount of fabric across the seat. Full coverage keeps everything contained, while a cheeky cut leaves more of the backside exposed. Many adjustable bottoms land in between, so the description matters more than the photo. If you want to stay fully covered, look for the words “full coverage”; if you want a sportier look, a cheeky cut with adjustable ties lets you pull the fabric to suit your comfort level.
Lining and opacity
Lining is an inner layer sewn into the front panel. A lined bottom stays opaque when wet, while an unlined one can turn sheer in the water. If you plan to swim rather than lounge, lining is the difference between a suit you trust and one you keep adjusting. When in doubt, choose a lined bottom — it costs very little and removes a common source of poolside discomfort.
Fabric weight and stretch
Fabric weight is how substantial the material feels in your hand. A thicker fabric holds its shape and stays opaque, while a very thin one can cling or reveal more than intended. Stretch lets the fabric move with you, and adjustable ties add a second layer of fit control on top of it. Together, weight and stretch determine whether a bottom feels secure through a swim or needs constant readjusting.
