There's no single design called a "training bra." First bras overlap with bralettes, sports bras, seamless pullovers, and other soft, wireless styles. The real question isn't which name sounds right — it's which one actually fits, feels good, and works with what your kid does all day.
Pick by what it needs to do, not the name
Ask four things: Is it easy to put on? How much coverage do they want? How much support do they need for movement? What seams, straps, or padding actually feel comfortable?
Seamless
Smooth, with fewer visible seams — good under fitted tops.

Sports bras
Built for movement — a solid first-bra pick for active kids.
Explore sports bras →Bralettes
Soft and simple, and often basically the same thing as a training bra.
Explore bralettes →Pullover
No back clasp, goes on over the head — simple, with less adjustability.
Explore pullover bras →Racerback
Straps angle toward the middle of the back — helps with some tops and activities.
Explore racerbacks →Padded or unpadded
Padding changes how much coverage and shape it gives — not whether it's a "real" first bra.
Padded guide → · Unpadded guide →Style, construction, and fabric are three different things
Racerback is about where the straps go. Pullover is about how it goes on. Seamless is about how it's built. Cotton is about the fabric. Padding is just an extra layer. So one single bra can be seamless, cotton-blend, padded, pullover, and racerback all at the same time — these words aren't rival categories, they're just different features.
That's worth knowing because it stops the labels from feeling more confusing than they need to be. Our construction guide covers straps, closures, seams, and pads, and our materials guide covers the actual fabrics.
The style you pick still needs to fit
Different designs feel different on the same body. A pullover style is easy to get on but gives you less control over the band. A racerback keeps straps in from the shoulders but can feel different around the neck. A sports bra holds things in place but can feel firmer. Whatever you pick, always finish with the 5-point fit check.
