Frequently Asked Questions (FAQs)

1. What age should I let my daughter wear a training bra?

“As soon as the breasts start growing breast buds, small (sometimes very tender) bumps below the nipples, is typically when girls start wearing training bras,” said Dr. Kronborg. “Normally, by the time a girl can fill a B cup is when she'll eventually require a standard bra.”

2. What is the best bra for 9 year olds?

Best Overall: Hanes Girls ComfortFlex Seamless Bralette 2-Pack. The Hanes Girls ComfortFlex Seamless Bralette is our top pick because it's soft and seamless, making it an ideal pick for young children who want some extra coverage.

3. What type of bra should a 10 year old wear?

Soft cup bras are a good choice for girls with small to medium-sized breasts. These bras do not have an underwire for support, but they do offer a soft foam cup to give smaller breasts a bit of padding and support. Girls with larger breasts may prefer to opt for an underwire bra.

4. What is the difference between a training bra and a bra?

Designed specifically for 'bra beginners', training bras look similar to normal bras, with a few possible differences: They often don't have cup sizes, which can be confusing and hard to calculate for beginners. They avoid under-wiring, which can be uncomfortable and strange to wear if a girl isn't used to it.
