It's just a well matched, cute avatar. If you want to get technical though, there's superheroines, villains, anime girls, etc that wear less. The majority of her chest is covered and her abdomen is covered, unlike with hookers. In fact, the only thing visible is her arms and a bit of her legs. So if that makes it a hooker, does that mean someone in a babydoll dress is a hooker? Someone in a tank top and shorts is a hooker? Because they are showing just about the same amount of skin. It doesn't matter, it's just an avatar but if that your opinion of women irl is anything like your opinion of something as simple as an avatar, that's pretty sad.
