In the infomercial these are worn by some woman as sports bras, with no shirt, but mine are see through! Maybe I should have got one size bigger or something cause when I put on a shirt it looks like I am wearing a sports bra, no separation, they are comfortable though. I would recommend them to everyone though because they are great to sleep in. I'm a DD and after I slept in one just one night my back didn't hurt when i woke up. Gave it 4 stars though cause it's not great for everyday wear like they say. Maybe they will work better for smaller cup sizes for day wear, but like I said maybe I need a bigger size for better separation, I bought large.
