It's just because he sits more than standing, he seemed like a person not sporting or go outside that much and it's all reading books and play computer so it's not strange for he has wide hips due to lack of exercise .

Yes It is possible, because I am almost like that only differece is I am not that small, my hips are big and wider than normal man but my other body is pretty slim compare to my hips.
And his collarbones and leg shape are that of a man just slim, that's pretty much a weak man's body. watch 2.1 and you would know what I mean.
