Top 20 female celebs with the smallest breasts – You need to see number 1! (With Pictures)

2. Rachel McAdams

Remember when Rachel McAdams played Regina in Mean Girls and had her tank top cut? Her purple bra was showing through, but she worked it anyway and then all the other girls started doing that too. Well, in real life Rachel could probably still get away with that because she is hot, fashionable, and successful. The actress has appeared in huge films lately, such as A Most Wanted Man and Southpaw. At 37 years of age she is making men and women everywhere swoon with her old-Hollywood glamour. She has never been involved in a nasty scandal or tasteless photo shoot, and that is something that we greatly admire.
