Actually i don't know why everyone is complaining abt what she's wearing. I thought it looks alright. It may look quite big at the bottom, but it doesn't really make her look fat. The top is a tube, which shows off her firm shoulders, shoulder bone and neck. If the top is made of some long sleeves and loose material, together with that bottom of the pants, yes then it'll probably look disastrous and fat.
Moreover, she added the pink belt as the accessory, without it the whole thing will most likely look horrible. I think she looks beautiful and it fits her
