Buying a 1920s men’s swimsuit is a trap for the uninitiated: vintage sizing runs small, some “swimsuits” are really costumes that shouldn’t touch water, and the difference between a look that lands and one that flops is often two inches of inseam. This guide cuts through that confusion, breaking down the best retro suits by real-world fit, fabric behavior when wet, and which one gives you the complete ensemble without a separate accessories run.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you’re dressing for a themed party or a vintage beach day, the right 1920s men’s swimsuit balances authentic stripes with modern comfort and a fit that flatters without embarrassing.
Our Picks at a Glance
How To Choose The Best 1920s Men’s Swimsuit
Picking a vintage swimsuit means deciding what you’re actually buying: a genuine two-piece suit built for the water, or a costume that’s closer to a theatrical prop. That choice drives everything — the fabric, the fit, and the accessories.
One-Piece Jumpsuit vs. Two-Piece Set
Authentic 1920s beachwear was often a single knitted jumper, while later vintage styles split into a separate top and shorts. One-piece jumpsuits read more accurate for a themed event, but they make bathroom breaks awkward. Two-piece sets let you move and mix pieces more practically for an all-day event.
Fabric Behavior: Knit vs. Costume Poly
A stretchable poly knit with lined shorts holds up to actual swimming, while unlined or semi-sheer costume polyester is best kept dry. Check whether the fabric is semi-sheer or the shorts are lined before you plan a polar plunge in it.
Sizing and Accessories
Vintage sizing runs small — many buyers size up at least one step, and taller men often struggle with the inseam-to-shoulder length. Also count what’s in the package: some costumes include a hat and mustache or pocket watch, while others name shorts and socks only.

In‑Depth Reviews
1. fun shack Old Time Bathing Suit Costume Men
Our pick — over 4★ from 250+ verified ratings; the strongest balance of quality and price.
The best budget pick for costume contests, offering the biggest laughs per dollar.
This one-piece gets the biggest laughs per dollar. It’s a classic old-timey look with a real velcro back closure — the front buttons are decorative — and buyers report better quality than your typical costume. A 5’10” owner with a 34-inch waist ordered a large and reports it fits great, while another wore it to a 1920s company holiday party and won best costume after adding yellow flippers.
It’s a proven laugh-getter, worn to a beach 4th of July and a Special Olympics plunge. Just know your conditions: it’s a costume, not a true swimsuit, made from semi-sheer polyester. Wet performance is uncertain, so owners recommend wearing swim trunks underneath for safety.
Keep expectations in check on extras — one order arrived without the advertised hat and mustache. And the one-piece design makes restroom breaks a project, a trade-off one owner called out while still calling it a great couples costume.
Laughs per dollar: the most costume-y feel here, ideal for parties and photo ops where comedy is the goal.
Not a swimsuit: semi-sheer polyester means this is for dry land and posing, not laps.
Grab it for: a themed party, polar plunge, or any event where you want to be the memorable guy.
skip it if: you plan to actually swim or you’re tall — the one-piece cut runs short for bigger frames.
2. Historical Emporium Men’s 1900s Striped Bathing Suit
The only water-ready pick with lined, drawstring shorts for real swimming.
This is the rare vintage suit that handles real water. It’s crafted from a stretchable 100% poly knit fabric with a crew-neck T-shirt and knee-length shorts, and the lined shorts come with a gathered elastic waist plus a drawstring so you can cinch a custom fit. Owners confirm the thick, quality material is public-worthy, with one buyer happily using it as real swim trunks in the ocean.
It beats the costume-tier options because it’s genuinely a two-piece swimsuit, not a one-piece jumpsuit. The deliberate oversized cut is a smart move — a buyer with a 34-inch waist found it fits comfortably, and the stripes align perfectly with the seams, which says a lot about the build quality. Material is what wins people over here: durable, breathable, and quick-drying.
There are two honest quirks. The navy and black colors look nearly identical — one owner wished they’d chosen the red — and there are no pockets, so a thin fanny pack is your friend. Colors can bleed when wet, which suggests it’s not primarily meant for submersion, but it’s still the strongest all-around choice on this list.
Sea-ready quality: a lined, drawstring two-piece that outclasses flimsy costume alternatives for both events and actual swimming.
Consider the catch: the dark colorways blur together and there’s no pocket; size up if you’re between sizes.
Reach for this if: you want one suit that works for a themed party and a real beach day.
Look elsewhere if: you need a pocket or a brighter navy that reads as blue at a glance.
3. Smiffys 20s Bathing Suit Costume, Blue & White
A complete blue-and-white set with hat and moustache, open-and-wear.
This blue-and-white short jumpsuit comes with the hat and moustache already in the box, so you’re party-ready the moment it arrives. The fit is accurate for a men’s bathing suit, and one owner confirmed it was the hit of an “Under the Sea” party — the moustache and hat complete the look. Chest measures 42″-44″ with a waist of 36″-38″ and a leg inseam of 33″.
It’s 100% poly with low stretch and a lightweight fabric weight, made by a family business with a 125-year heritage in costumes. The true-to-size sentiment is backed by buyers reporting a great fit. It’s goofy and fun by design — one husband wore it to work and “people couldn’t get enough of it.”
The low-stretch fabric means it won’t give much on a muscular or larger frame, so sizing up is wise. Also note the included components are the hat and shorts, with the moustache as the third piece — everything else is on you.
Open-and-wear: a full striped set with hat and moustache, no accessories shopping needed.
Mind the stretch: low-stretch poly is less forgiving, so check your chest and waist against the listed specs.
Best for: anyone who wants a complete photo-ready look with minimal effort.
Not for: athletic builds that need stretch, or anyone between sizes without room to grow.
4. Karnival Costumes Old Time 20s Bathing Suit
The complete one-piece jumpsuit with hat and mustache, ready for stage or party.
This one-piece costume includes the jumpsuit, mustache, and hat, giving you a complete 1920s getup straight from the start. It was a hit for a theater group and one reviewer noted “dripping sex appeal in to lake Superior,” while a bigger guy confirmed it fit well. It weighs 1.54 pounds, which tells you it has some fabric to it.
Compare it to the fun shack: both are one-piece jumpsuits, but Karnival includes the hat and mustache where fun shack sometimes ships without them. That makes this the more reliable full-ensemble choice. It also gapped slightly at the neck in back for the theater group, though the rest fit fine.
The honest limits are sizing and condition. Owners mention it runs small and is hard to pull on and off, with one tall owner saying “needs at minimum 12″ added from inseam to shoulders” — so it’s not for anyone over 6 feet. And one order arrived clearly used with a stain on the front, so inspect it on arrival.
Complete costume: jumpsuit, hat, and mustache in one purchase, ready for stage or party.
Size up: runs small and short, so it’s a no-go for taller men.
Choose this if: you want the full one-piece ensemble included and you’re under 6 feet.
Think twice if: you’re tall or you want a true-to-size fit without wrestling into it.
5. SATINIOR 1920s Mens Costume Outfit
The accessory-rich ensemble with vest, watch, and ties for a layered 1920s look.
The crowd favorite detail is the appearance: buyers rave about how the accessories bring the 20s vibe together, and the XL fits a 237lb muscular man perfectly. The lined vest is a step above typical costume quality.
It’s great for themed parties — one buyer’s 15-year-old loved the mustaches and entertained everyone, and a stage performer added rhinestones for shows. The metal pocket watch and multiple ties give you layered options that no other pick here matches. With black, wine red, blue, gray, white, and brown colorways plus sizes L to XXL, there’s real choice.
The trade-offs are honest: fit gets mixed feedback, with a 2XL running snug on a 2XL wearer, and the hat arrives folded and needs steaming to lose its wrinkles. Some orders came missing the pocket watch and mustaches — though replacements completed the set. The hat is also one-size across all suit sizes.
Accessory value: vest, watch, suspenders, and ties make this the richest ensemble for a party.
Fit is mixed: it runs small for some, and the hat needs steaming plus a single size fits all.
Perfect if: you want a layered, accessory-heavy costume that photographs beautifully.
Skip if: you’re between sizes or you need a hat that fits a larger head comfortably.
6. Forum Novelties Men’s Roaring 20’s Beachside Clyde Costume
The funniest pick here, guaranteed to draw laughs at any 20s party.
This set includes a blue striped shirt, shorts, and socks, and it’s pure comedy gold. One husband wore it to a roaring 20s New Year’s Eve party and stole the show, while another tied for best costume of the night. Customers note the top and shorts fit well and the material is comfortable to wear, with one noting a perfect fit for their husband.
It’s a laugh-getter that makes you stand out from standard suits at any party. Forum Novelties has been in the costume business for more than 30 years, offering over 8,000 items, so this isn’t a fly-by-night design.
The recurring gripe is the socks: they won’t stay up, they’re not actual socks, and one order arrived with no socks at all. Quality and fit get mixed feedback, with one buyer finding the fabric uncomfortable and the shorts too long, though others say it worked perfectly. It’s a costume, not a swimsuit, so keep it on dry land.
Show-stopper: the funniest pick here, guaranteed to draw laughs at any 20s party.
Sock problem: the stockings are notoriously hard to keep up, so budget for replacements.
Wear it for: a party where the goal is comedy and maximum laughs.
Pass if: you want a serious swimsuit or you can’t tolerate fiddly socks.
Understanding the Specs
Fabric Type and Water Readiness
A stretchable 100% poly knit with lined shorts is your green light for real swimming. Unlined or semi-sheer polyester means the suit is best for dry-land posing. Always check if the shorts are lined before committing to a water event like a polar plunge.
Fit and Vintage Sizing
Vintage cuts run small and short. Look for suits labeled “oversized” or “relaxed fit” for breathing room, and size up one step if you’re between sizes. Taller men should check the inseam-to-shoulder length on one-piece jumpsuits before buying.
