Girls First Bra | Firefly Hybrid | Yellowberry Company

Firefly Hybrid

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 cotton 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)

Awesome first bra and very sweet packaging

My daughter was hesitant to buy a bra, but Yellowberry made shopping a fun experience. I love the wrapped gift box and sweet note that cake with her bra.


My 12 y.o. daughter absolutely loves the Firefly Hybrid bra! We've tried so many store styles (with those horrible pads)..always hoping for THAT fit. You know the fit moms. When you slip it on everything just feels RIGHT. That is the Firefly Hybrid. Comfortable, secure and stylish. One of my best purchases! For reference, my daughter's chest measurement is 26. We ordered a small.


Bought this for my granddaughter. She loves it. It fits perfect and it is very well made.

Great Bra for sports

I wear this to play soccer. It doesn’t move around and keeps me fairly dry. The pieces to adjust the strap length can be uncomfortable.

Active 15yo ✔️

My very active 15yo wears only sports bras and this one passed her test. She fits LG in all other YB styles but MD in this style. We would buy more colors.
