Yeah, it's obvious that girls chests are bigger than they would naturally be, as they are trying to attract the 12-18 year old male crowd. There's no reason that Laura Croft, the girl on the Everquest box or any other character has to wear half revealing clothes. It's unrealistic to think that an adventuring girl is going to show her navel, yet wear three inch thick steel armor on her arms and chest, yet leaving a big spot open to show off her cleavage.
