I start to suspect that this kind of body is considered "hot" over there in US, just because most of other females are like.. triple of this size. She'd be considered a legit fatass in Europe, and I don't even want to imagine how she'd look like a after a kid or two..
Slim legs, small ankles/joints, nice, round small bubble butt, that looks good in clothes and doggy style too.
edit: oh I forgot - LONG fingers.. one of the indicators a female will stay slim as the years goes by.
