Put it this way. I am 5'10" and I weigh 147 when I am scheduled for fights. I would say she's probably a pretty curvy road, buddy.
There is a huge difference from a fighters weight compared to a regular persons weight. When I used to fight, I would come in around 155 lbs at 5'8-3/4 and now I walk around at 185. I basically look like the same person, just thicker now. A lot of the college girl volleyball players I play volleyball with are around that height and weight and most of them look very nice. They normally have muscular legs and muscular/ larger butts from the jumping. I guess that's where the extra weight is at.
Who knows, maybe she is decent looking or looks like a McDonald frequent flyer. Either way, the OP should not be too picky.
