What a first bra should feel like
A first bra is optional until the wearer wants or needs one. HealthyChildren.org advises caregivers to be willing to buy a training bra when a young person requests one or could use one; development does not follow a fixed age timetable.

How to measure and check fit
The Center for Young Women’s Health at Boston Children’s Hospital recommends using an underbust and bust measurement as a starting point, then trying bras on because nominal sizes vary by brand and style. Its 2025 guide reports that nearly 50% of bra wearers are in the wrong size; that figure belongs to the guide and is not an independently reviewed prevalence study.
- Measure around the rib cage directly under the breasts with the tape level and comfortably snug.
- Measure around the fullest part of the bust without compressing tissue.
- Use the specific brand’s size chart; do not assume another brand’s size will match.
- Try the garment on, if possible, with normal clothing and with arms raised, bent and moving.
- Recheck after washing according to the care label, since fabric stretch and fit can change.
For a growing wearer, reassess fit whenever the band feels tight, cups gape or spill, straps need constant tightening, or movement becomes uncomfortable. If alpha sizing no longer gives enough support, compare the brand’s band-and-cup options or its women’s range rather than sizing up blindly.

Choose sports-bra support by activity
Support should match the movement, not simply the product’s marketing label. Nike’s teen guide recommends:
| Activity | Nike’s suggested support category | Fit checks |
|---|---|---|
| Yoga, Pilates or relaxed wear | Light support | Look for unrestricted breathing and no shifting during stretches. |
| Strength training or gym sessions | Medium support | Check that the band and straps stay stable through lifting and bending. |
| Running, jumping or HIIT | High support | Look for secure containment without painful compression or chafing. |
These are Nike’s recommendations, not a universal medical standard. Bras for Girls identifies personal comfort, activity level, support, fabric and design as key fit factors. A sports bra should allow full movement and should not cause numbness, rubbing or restricted breathing.

Uneven development and common health questions
Is uneven breast growth normal?
Yes. HealthyChildren.org states that “Breast size is seldom symmetrical.” Temporary or persistent differences are common while breasts develop. A bra can be fitted to the larger side for comfort; removable pads can also help with appearance if the wearer wants that.
Can wearing a bra affect breast growth?
No. Nemours KidsHealth, medically reviewed by Amy W. Anzilotti, MD, says, “A bra won’t affect breast growth.” Genes and hormones control development. A correctly sized, comfortable bra may improve comfort but does not speed up, stop or reshape growth.

When should a clinician be contacted?
HealthyChildren.org recommends a well-fitted support or sports bra for breast pain, especially with exercise. Seek medical advice for a lump, persistent pain, worsening symptoms or another change that concerns the wearer. Shopping guidance is not a substitute for an examination.
