NEW Firefly Hybrid - Yellowberry

NEW Firefly Hybrid

Size Guide
Active Bra Size Guide

Our Newest Favorite. A splendid update to the traditional racerback style. We added width on the back panel design to give exceptional support for girls at any stage of development. Fabric is sleek, feels like silk and wears like iron. Think soft, supportive, and strong.

Fit.    Our   Hybrid Firefly Bras are meant to fit more tightly than our other styles. If you are in between sizes or your daughter prefers a less snug fit, please size up to the next size.

Innovative, Hybrid Technology.  What's that?  We invented a brand new bra category after listening to your feedback: Girls wanted a bra they could wear all day, every day and never have to change. These styles are designed to move with her from math class to soccer practice with ease.

No Padding Needed, Ever!  Every Yellowberry Bra is double layered with high-quality fabric to ensure full coverage and support, always.

Great For girls who are active. Anywhere from the first bra wearer to those looking for an exceptional new style. 

Different From the Willow and  Aspen bras because of the fabric. The  Willow and  Aspen are both made in cotton, but the  Aspen is a thicker material. The Firefly is made in our Innovative Hybrid Material. More active? Choose the Firefly. Everyday bra? Willow or  Aspen. Most coverage in cotton?  Aspen.

  • Nylon / Spandex fabric blend
  • Antimicrobial and moisture-wicking
  • Matte brushed finish for absolute comfort and softness
  • Machine wash and dry (to make everyone’s life easier)

Great fit

The hybrid firefly has a great fit!!

Tighter than aspen

My daughter did not prefer this bra, she found it tighter than the aspen, which is her favorite . Nicely made but fits differently.


I had sent the XL Bras back about 3 weeks ago requesting that the next size down L replace those sent back. Could you please check on my order. Thank you! Gloria Daniels
