So, I bought two new lace bras for Christmas because I needed something to wear with a thin tee. Well, the bras are almost like sports bras, therefore they have no support at all. I've been wearing them both for about two weeks and I finally decided to wear a normal bra because I was starting to have back aches. Ever since I started wearing a normal bra, my nipples have been sore. Does anybody else have this problem or experienced it?
