The stance has had me baffled for ages. I did it once, stood with my legs that far apart and I was almost on the floor. I'm not skinny by any means but I would never ever stand like that to show off an outfit. Stand normally, one leg in front of the other, not like a weightlifter.
Also, short chunky thigh-have-r here, would never ever wear cut off wide jeans like that. Absolutely unflattering to our body shape. Why doesn't she know anything? She could look cute.
