Favorite running bra

I’ve been searching for a running bra that has an adjustable band and this is THE one. I always have an issue with bands being too tight or too loose and never “just right”. This bra solves the issue. Feels easy to breathe while running! Also easy to take off. I’m 5’0” 115lb 30A and ordered size 2.

Am I in heaven?

WOW originally I thought — how will I put this on with a back clasp but it was SO EASY. It's so freaking cute and I love the support + vent in the back

You have to give it a try!

This is my favorite running bra I have ever tried!!! I'm a size 34/36C and I wear a size 6 in all things Oiselle. My previous favorite was the hi 20 bra and while I still love her, I prefer the higher cut of the squared up bra. The squared up genuinely feels like a hug without feeling too restricting. I love the breathability of the open back, and the straps are the perfect width. I also love how simple the design is and the combo of functionality and style. I love it so much I got it in two colors!! You have to try!!!!

Great Bra

Love this bra! It’s comfortable for running and it’s flattering. 34C/size 8.
