Here’s no magic number for when to start wearing a bra. Most girls get their first bra somewhere between 8 and 14, but it’s all about your body—not your birthday. Some are ready at 8, others at 15, and both are totally normal. This is a big milestone in every girl’s life, and it’s important to choose a brand that understands your needs.
Signs You Need to Get Your First Bra
-
Breast buds show up: Small, sometimes sore bumps under your nipples? That’s a sign of breast growth and one of the first physical changes of puberty, usually between ages 8 and 13.
-
Things show through clothes: If your nipples or the shape of your chest are visible under shirts, you might want a bra for coverage and confidence.
-
Movement feels weird: If running, jumping, or physical activities make your chest feel uncomfortable or bounce, a bra can provide extra support.
-
You feel self-conscious: If you’re a first-time bra wearer or feel awkward changing in front of others, a pad or lined bra can help you feel more secure under any outfit.
Why Are Girls Starting and Body Changes Puberty Earlier?
Scientists have noticed girls are going through puberty and body changes like breast development earlier than before. Some girls start as young as 6 or 7, especially if they have a higher body weight or certain genetics. Hormone changes can also play a big role. Here’s a quick look:
| Group | Average Age for Breast Buds |
|---|---|
| African American girls | 8.8 years |
| Hispanic girls | 9.3 years |
| White/Asian girls | 9.7 years |

If you’re developing earlier than your friends, you’re not alone.

How to Find Your Perfect Fit
Getting the right bra size is key for comfort and confidence. Many moms get their daughter’s first bra size wrong, so don’t skip this step:
-
Band Size: Wrap a soft tape measure around your ribcage, just under your bust.
-
Bust Size: Measure around the fullest part of your chest.
-
Cup Size: Subtract your band size from your bust size (each inch difference = one cup size).
Here are simple first bra fitting tips to help you out.
Do You Have to Wear a Bra at a Certain Age?
Nope! There’s no rule that says you must wear a bra by a certain age. Some girls want one because their friends have one, but you should only start when you feel ready and your body shows the signs. If you’re unsure, it’s totally normal to wait.

-
Support: Bras are designed to help with movement and keep things comfortable, especially during physical changes and activities.
-
Confidence: The right bra can empower you and help you feel good in your clothes.
