I am a braless girl, mostly because I spend a lot of time at home now. I have TWO really nice DD Victoria Secret bras that are indeed uncomfortable, but I love the support and beauty of the bras and how they make my boobs look, lol.
That aside, I saw an infomercial for this:
Miracle Bamboo Bra and it was a total GODSEND for me. I bought three and never looked back. However, my mom hated them because she was much bigger and the straps were too loose for her, I guess its not for everybody. But I love mine and those are the most comfortable bras for me when I am just "roughin" it, lol.
