Hey Fan, I'd go larger, especially with a D cup as most commercial patterns are made for B-C cups these days. I bought a Eurotard mesh middle leotard in a size large and I really could have used an extra large. You probably should ask the company you choose if they line their tops....mine is lined and it flattens my B's into nonexistence! In other words, a lined top might give you uniboob or worse, squish things from under it, which incidentally happened to me the one time I didn't wear a regular bra with it. Thank goodness no nipples made an appearance! Honestly, the home made tops are so much more comfortable and they're easier when nature calls. If you have a friend with some sewing skills maybe you could swap? If we were closer I'd help you out for sure....I hate to see friends uncomfortable or unhappy with what they're wearing! Just another thought...my teacher wears normal light weight tops with Turkish vests. She always looks nice and the vest helps us out visually when we're working on upper body isolations. There's the added bonus of fun with coordinating colors!
