I think that in this picture, the other girl looks kind of awkward and it is height-related.

We are the same height though and I don't think I look awkwardly tall in lolita. D;
It's just her skirt length and there is nothing to draw attention to her upper half because of the black, simple top so there is too much attention on her legs. :3 Boots also help to make your legs look a little shorter... Just use general style rules and you should look fine. ^ ^
