Most Helpful Guy
To my eye:
1-3 are all slim and attractive
4 looks shopped to me. Maybe it's the angle, I don't know. In theory grils around 4 - slim with an ass are very attractive to me.
5-6 are fat, though both carry it better than the average woman their weight.

Why is there no average? 1, 2, and 3 look unhealthily thin. 2 is ok, but 1 and 3 look like pictures you'd see on a pro-anorexia blog. 4 has an unproportionally big butt and an unnaturally small waist, and 5 and 6 are a little curvier than the majority of girls I know. I'd say 5 is the closest to average, except with not so huge boobs and a little bit slimmer.
