A pull-on with permanently placed foam padding that stays secure during active play and laundry.

If your daughter is past the very first training stage and wants a little more coverage, this is the step up. The defining feature is the foam that is permanently placed in the cups — no sliding, no crinkling, no re-inserting after laundry. Buyers report the padding stays exactly where it should even during active play, and the softness earns almost as much praise as the secure fit. It’s the kind of bra that works under thin uniform shirts without showing through.

It pulls over the head with no back clasp, a huge win for preteens who don’t want the hassle of hooks. The fabric is 80% Nylon and 20% Spandex, giving it a smooth, smooth look under clothes. For a 12-year-old at 148 lbs, the XXL fits great, though a few parents wish an XXXL existed for bigger builds. The colors are soft and neutral enough to work with any top, and the quality seams mean no itchy tags against sensitive skin.

A smooth 2-pack with adjustable straps that extend to fit her as she grows.

Fruit of the Loom brings decades of underwear expertise to the training bra game, and it shows in the thoughtful details. The adjustable straps can be lengthened as your daughter grows, so this 2-pack can stretch from one school year into the next. The smooth fabric is soft and smooth, and the removable modesty pads are easier to pop in and out than most — a detail parents specifically call out as better than other brands.

The sizing is where you need to be careful. A 27-inch chest maps to a size 32 and fits perfectly, but the same size runs tight on some girls, so check the chart rather than guessing by age. It’s stretchy enough that a petite 23-year-old at 32A even uses it as a sports bra, which tells you the coverage is real. The main gripe is the same one that follows all removable pads: they shift around in the wash, so plan to take them out before laundering.

A smooth 6-pack sports bra with adjustable straps and removable pads for active days.

For the active 13-year-old, this 6-pack is built around movement. The smooth sports bra design means no bra lines under tight tops, and the fabric has just enough spandex to allow unrestricted motion. The adjustable straps and removable “cookies” — the little foam pads — let her customize the fit and the coverage. A 10-year-old softball catcher wears the L perfectly, which tells you the fit runs true for athletic builds.

The star detail and the prints on the sides are a hit with girls who want something fun, not plain. The biggest recurring note is the padding size — the pads are significantly smaller than the pocket they sit in, so they slide around and sometimes twist in the wash. Several parents simply remove them and wear the bra unpadded, which works fine since the fabric is thick enough to prevent see-through. The XL size chart runs about two inches small, so size up if she’s on the taller side.

An 8-pack of unpadded, tag-free pull-ons with no wires or hooks for fuss-free rotation.

This 8-pack is the ultimate set-and-forget option — eight bras that cost about what one premium bra goes for elsewhere, giving you a full week of rotation. The design strips away everything: no wires, no hooks, no clasps, no padding. Just a smooth, smooth pull-on with slim spaghetti straps and a tag-free interior that rests comfortably on sensitive shoulders. It’s the “sensory texture test” winner among picky kids, passing the softness check that matters most.

The fabric is a stretchy nylon blend that feels cool in summer and is pool-safe, though the trade-off is that it’s on the thin side. The quality of the construction is solid, and the colors are varied enough for concealment under white school shirts. It runs slightly small — one parent notes a skinny 8-year-old needed a bigger size than expected — and there’s no back adjustability, so the fit is what you get. For a single 13-year-old, an 8-pack means she never runs out of clean bras, which is the whole point.

A 6-pack of assorted printed pull-ons with soft, lightweight fabric for younger teens.

These are the bras that make getting dressed something to look forward to. The pack delivers six randomly selected prints pulled from a rotating vault of designs, so every delivery is a little surprise — one granddaughter wanted sharks and got the princess instead, and she loved it anyway. The vibrant colors and soft, lightweight fabric don’t dig into shoulders or chest, which is the comfort detail that comes up most. The racerback or cami styles work for both daily wear and light workouts.

Value is the story here, with six bras at a price that undercuts most single-bra options. The fabric has enough stretch that a 4-year-old in 5T can wear them, which speaks to the forgiving fit, though the sizing is mixed for older kids — some find them true to size while others say they run small. There’s no padding at all, which makes them ideal for the very first training stage, and the thick fabric prevents see-through. Durability is a mixed bag; one strap latch tore during use, so treat them gently in the wash.

A soft, breathable cotton pullover cami with spaghetti straps for a gentle first-bra introduction.

For the very first step into bras, this 4-pack from Fruit of the Loom is about one thing: gentle introduction. The soft, breathable cotton fabric is comfortable and lightweight, and the pullover cami style with spaghetti straps is easy for a young teen to manage on her own. The colorful prints make it fun to pick one for the day, which takes the awkwardness out of the transition. It’s the kind of beginner bra that “gets them used to the feeling of wearing a bra” without overwhelming them.

The catch is that the material is thinner than expected and not actually cotton-heavy despite the name — and it’s not double-layered in the front. There’s no padding and no strap adjustment, so the fit is fixed once you buy it. Some parents find the straps too long for smaller girls, with no way to shorten them. The sizing is mixed true-to-size versus runs small, so measure before ordering. It washes well without shrinking, which is a plus for a budget pick.

A step toward real bra sizes, with cup letters instead of just age ranges.

This bralette is different from the rest because it uses actual bra sizing — 32A through 38A — rather than a generic S/M/L. That makes it a useful bridge for a 13-year-old who has outgrown training bras and wants something that fits like a real bra. The triangle cup design provides a bit more shape, and the back clasp gives her the experience of a grown-up bra without the underwire. The quality and style earn consistent praise, and the soft, durable material fits true to size for many.

The fit is where opinions split. Some find the sizes run small — one buyer ordered a 36 and got what felt like a 34 — while others say the sizing varies within the same pack. The comfort is also mixed, with a few describing the material as stiff and itchy against sensitive skin. Durability is the bigger concern, with reports of straps coming loose and clasps coming undone over time. It’s a decent budget option if your daughter wants the look of a real bra, but it’s not the most reliable pick for daily heavy use.

A cotton-rich back-clasp bra with three hook positions to fine-tune the fit.

This is the most traditional bra on the list, and for some 13-year-olds that’s exactly what they want. The 95% Cotton and 5% Spandex fabric is breathable and soft, and the classic back button with three hook-and-eye positions lets you adjust the band across three sizes. That adjustability is a genuine plus for a growing teen — as she changes, the bra can change with her across those three hook settings. The light padding is fixed, so there’s no fuss with removable pads in the wash.

The cotton content makes it cooler and more breathable than synthetic blends, which matters for all-day school wear. The catch is the sizing, which runs consistently small. A 13-year-old in a 32A found the size 32 far too small and had to return for a 34, which was still snug. One parent bought extenders to make the band work rather than exchange again. The quality, comfort, and value all earn positive feedback when the size is right, so measure carefully and consider sizing up.
