Re: US Open outfits!
Serena's dress is too short.
It's not that her butt is hanging out. But it cuts off at the wrong spot. It needs to hang more. It seriously looks like somebody hemmed it to make it shorter and picked the wrong spot to fold the hem. If you've hemmed a skirt or a dress you know what I mean.
I don't think it is the size of her butt, because the back is the same length as the front. If you have a big butt, sometimes the back will be shorter. Do you think Nike custom cuts her skirts so they hang evenly?
