Not true to size

Bought this sports bra in a 32D based on reviews that said it is "true to VS sizes", but I did not find this to be true. My VS size is 32D, but the cup size on this bra is huge. I plan on returning it, but I'm debating going down to a B or C cup size (it's really that big). Chest size fits perfect though. I do love that it functions like a regular bra with the back closure since I do the "sports bra hop" to get out of my other MC bras. I just can't give it a better rating because I can't wear it in the size I got.
