This was my first time wearing these. I felt these were going to show through the shirt I was planning to wear. After putting them on, they were not hard to stick on. I put the shirt on and you could not see them at all. It felt great as I was not really wearing them. I highly recommend wearing these if you want to go braless. They are perfect for those who do not want to show nipple while cold outside. These are reusable, but when you take them off, they can be a bit painful, just FYI. Overall, very good product!
