I bought the pink/black/white lace trim version. I am a 36B/C and bought the 38 because I cannot stand tight bras. I also thought since these were cotton, that would be a safe bet and I was right. These are super cute and work well when you have a top that is cut a little low. They are fairly thick material, so they are not see-through, and it is easy enough to throw in a couple pads for headlight coverage, if needed. If you need a simple, comfy cotton blend bra, I think this fits the bill. These are my go-to bras if I don't need a racerback style.
