I ordered a 32 H, I probably should’ve gone a size up, but dear god, it looked like the bra was for a 32 C!! It was tiny!

I sized up in band size as per recommendation, and I could fit a fist underneath the band and still had room to spare, so way too big! This of course also compromised the support it gave me so I can't give an honest review on that. So, unfortunately, I need to return, which sucks as my old sports bra has broken down.
