According to the GF women, well the avg woman only has like 5-6 bra's and they don't change them daily.
This is shocking to me, I'm an ass man, but the boobies are a close friend. I always thought they were changed daily like the lower section of underwear, wow, wowwwww, OMG wow. I will now support the bra buying habit, even though the GF doesn't have one. I like the boobies, and they will be clothed in awesomeness.
