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)

Super comfy!

Love how it doesn’t shrink or misshapen after washings and maintains its softness and brightness!

My daughter loves it

It immediately became my daughters favorite bra. She has requested more.

Daughter loves it!

My daughter really likes this bra. It’s a great neutral color. The sizing is a little on the small size. Fabric isn’t as flexible as her favorite Aspen bra so be sure to measure.

Great Fit

My daughter loves this bra. She says that it is super comfy and is always a great fit for her.

One of the best!

My 11 year old loves the Firefly Hybrid so much. It's so soft and and doesn't budge one bit. We love the nude colors -- they disappear under all shirts. I was nervous about sizing for our first order but measured her and followed the measurement guidelines. She's tall and slender and started to develop last year. The small is perfect. Don't hesitate on this one!
