Most Helpful Guy
Depends on whether I'm in front or behind her.
If I see her from the front, it's all about whether her face is at least cute. Not too picky, just has to be pretty.
If I see her from the back, it's all about a mix of her butt and her overall shape. If she is very petite, a small ass is OK because "petite" is incredibly sexy to me. But otherwise, she needs an ass. However, I will quickly require a facial confirmation that she is good looking...
I would say that breasts usually don't play a strong role for me early on. I'd say: Face/slim is important, followed by butt, height, clothing, and then the rest.
