🎀 First Bra Guide for Teens and Tweens

A first bra is about comfort and confidence, not size. Start with bralettes, training bras, or soft-cup styles.

When to start

Around the time of breast budding (typically ages 9–12). There is no fixed age — comfort matters most.

Best first bras

Soft cotton bralettes, training bras (no underwire), or seamless racerback styles. Avoid underwire for the first year of breast development.

Sizing teens

Use S/M/L sizing for first bras. Move to numeric sizing once breast development plateaus.

Frequently Asked Questions

Should teens get professionally fitted?
Yes — once development is well underway. A good fitter ensures a comfortable, confidence-building experience.
