Small band, big busted ladies can rejoice!
This is the most comfortable, most supportive bra I've used since post breastfeeding and ending up with DD tatas. I'm between a 30-32 band and got the XS D-DD. It's perfect. I looked at this bra a few months back thinking "no way is that going to work with the elastic band in the back". Y'all. IT DOES! I'm not sure what kind of sorcery is at play here, but the racerback design keeps everything from bouncing, and you feel locked and loaded during your run. The elastic band helps you freaking breathe?? I love breathing during runs! Yes, you will get uni-boob. No, you won't care. This bra feels light as air, gives great coverage on the sides and on the upper chest so you never feel like you're spilling out. The band is thick and wide, like a long line bra. Just buy it!
Good bra
TTS. Needed a new running bra and decided to give this one a try. Went on a quick run today and it was comfortable and kept the bounce at a minimum. I think this bra is worth checking out!
love this bra!!!
New favorite bra!!! I am 34DD AND I GOT A L. I like a lot of support but I also want it to look hot! I like how it looks and feels!
Best Sports Bra
I have tried many sports bras over the years and none have ever fit, supported and felt feminine before. I am a 34D so I need a lot of support.
