For a white bikini top with the pads taken out it is NOT see through. Naturally if your nipples get hard there is going to be an outline of them however you cannot see color difference between boob and ariola.  I am a 36C and the small top fit better than expected. The bottoms on the other hand were bigger than I would have liked but look good non the less. The back schrunching detail always makes your butt look better. I wish this bikini was available to mix and match. I will definitely be buying more colors.
