Relentless Sports Bra - Hydrangea Blue Large (12)
Lovely bra but I don't think it's suitable for naturally larger busted women. I'm a 34DD and bought a larger size to get coverage but the back is a bit too big for me and the cups don't fully cover my boobs, so I can't wear it for a workout unfortunately.

Nice bra felt a bit strange at first . The band at the back felt like I needed to keep pulling it down . Maybe it's just me but a really nice bra.

Relentless Sports Bra - Black Medium (10)
I love this style! However, based on my measurements (equivalent to bra size 8GG) the size calculator recommended I buy an XL 🤷‍♀️ I settled on a M and it is still too large. The size calculator for bottoms worked well, but I would exercise caution when using the calculator for sports bras.

Relentless Sports Bra - Black Medium (10)
It looks so good from the front! Not really a fan of the cut in the back though. It runs rather small and is VERY tight, better size up!
