As long as I don't see an ass-crack, I really could not give a trout. Girls walk around with breasts coming up through tops and asses nearly hanging out of shorts, skirts and dresses. This is clothing that is showing. I could honestly not care less. Women do a lot worse with panties and bras and I think it's sexist to tell men to cover themselves up when women aren't bothered to do the same.

If you are offended, that is your own business. Society shouldn't cater to protecting the feelings of people who are bothered by clothing trends. Let the idiots walk around with their pants down to their knees if they feel like it.
