As you can see from the pic, these are nipple covers – for all your super sheer comfy bras that provide no coverage. I like these because I have a habit of changing into these fabulous but thin sports bra tanks that I got from nordstrom rack at night (they are comfortable enough to sleep in) but even with a dark tee on top.. They always show! I can’t leave the house with the faintest "high beams" so these are perfect.. They warm up and you WILL forget that you are wearing them, but try not to.. Your ladies must breathe overnight.. Washable.. Very thin at the edges so be careful you don’t tear em. A nice gift for the modest girl friend. About $26 at http://www.amazon.com
