Being short does help, actually. The narrow hips are much less noticeable if you're short. Also, being petite is a HUGE factor. I wish I could show you a picture of me by one of my trans friends (I wont because it's not respectful to her). She's not big at all (in fact she's 3" taller than me and weighs just as much), but next to her I look tiny. Her shoulders are much more broad, and side by side the picture would be worth a thousand words. The broader girls tend to pack muscle a bit more, too. That really hurts with the cute factor, unfortunately.
