Flattering, supportive, don't want to take it off

I am a 32DDD and I bought a medium. It fits great! Snug in a good way, holds me in surprisingly well for interval/functional training. The material is great. Thick and quality. My only reason for not giving it 5 stars is that the straps on my shoulders get twisted easily. I love it though! Looks great, too.

Just OK

I saw that this sports bra was recommended by BP for higher impact/larger chests. Sadly, this wasn't the case for me. Size 32DDD and bought in my normal size - Small. I can't size up to Medium or the band won't be tight enough around my ribcage. Worked out in this sports bra and my chest was spilling out over the top of it. Cute for lounging or wearing out if you want some cleavage. Not for high impact workouts.

So comfortable

This is my second bra with this design. Feels comfortable, doesn’t dig in and has great support. Very athletic feel.

FIT GUIDELINES:

Every bra serves a different purpose for different activities and we recommend referencing each specific bra product description to determine the best bra for your body and sport. Our bras should generally fit snug. Wearing the bras too loose will not likely provide adequate support.

***Please note, a majority of our sports bras are medium support and medium coverage. If you are looking for the highest impact support that we offer; check out the X-Factor, Intensity or Moxie Sports Bra!
