Where the word "bra" comes from: First introduced in 1907 in Vogue magazine, the term "Brassiere" means "support" in French, but was shortened to "bra" for easy reference.

The push-up bra was invented by a man, of course: The push-up bra was created in 1947 by Frederick Mellinger. He is the man behind Frederick's of Hollywood and is responsible for putting out the first padded push-up bra called "The Rising Star."

Cup sizes are going up: Compared to 1996 when the average woman was a 34B, sizes have risen. Now some women have an average cup size of 36 DD.

They prevent saggy boobs: Wearing a bra–even if you have small breasts–delays the sagging process. Since there is no muscle memory in the area the bra can help you benefit from it.

Neck and shoulder pain can be bra-related: If you are wearing the wrong bra size the weight of your breasts will not be evenly distributed and can lead to back or shoulder pain.
