The "ideal" weight for a 5'1" woman would be about 105 lbs - so at 85 lbs she is at least 20 lbs underweight (and 105 lbs would be on the very skinny side of normal.) I am 5'2" and I have been my so-called "ideal" of 110, but at 110 lbs people are asking me if I am OK - 120 is my perfect weight because I look healthier. So I'd say Nicole would probably look great at 115 lbs. and is/was 30 lbs underweight.
