sometimes when you are going braless, or when your nipples are hard, or when your bra is too thin, or whatever the case is, your nipples can be seen poking through your shirt. girls, do you mind this? does it make you feel self conscious? why or why not?
also, why are so many bras so thin that they allow nipples to poke out in US? i noticed that in asia, this is almost never the case.
