OK, so first off I have to say that I have such a poisoned eye for those dangling pocket bottoms. HATE it.
That said, I do like that she used jeans that are wide in the thigh. I think that is the key. It's why I can never make shorts out of my old jeans - my new BF jeans aside, all of my jeans are fitted in the thighs, which I like for pants but I prefer my shorts to be loose in the thigh.
