I typically dread summer because with any form fitting tshirt my nipples would show through the shirt so I could never wear them. I was nervous with these at first thinking it was just going to lay over the nipple and create a bulge instead. I was pleasantly surprised to find out that they not only cover, but they flatten out your nipple too so there is absolutely no bulge from both the nipple or the sticker. Smooths your chest right out. Perfect.
