These are sooooooo awesome.  I wear them everyday to work M-F.  My nipples standout through multiple pieces of clothing and I was tired of wearing padded bras or trying to figure out what I could wear without my nipples sticking out.  These Top Hats stay on really good and I've even worn them without a bra once. I've been wearing them almost daily since I bought them (months ago?)  and they still stay on.  I'll be buying them again, FOR SURE.
