Missus Mustache
But why? You can show as much boob as you want on television and on the beach or wherever as long as your nipples are covered, ever notice that?
It's a social taboo for a woman to expose herself completely to the n****e, mostly because our society always will be a little prudent about things like that, 50 years ago, it would have been considered risque to even show the slightest bit of cleavage, mainly due to our forefathers mostly being puritan settlers, their ingrained ideals are in us still, but with time, I do anticipate that we'll drop our social pretenses and girls will be accepted as being topless just as often as guys are, just give it time.
