I have been wearing these for years in the same size and purchased them from several stores including Amazon. I tried to stock up at the great $12.99 price, but these are very different. the band is tighter and the cups have crazy wrinkling at the top that show through shirts. I had an old one with the tags still on and compared it to the one I just purchased and the sizing is very different. I ended up getting a smaller cup size compared to my usual and that got rid of some of the wrinkling. there is also something very scratchy at the back of the band. wondering if these are knock offs or something.
