Petite is any female under five four inches, has nothing to do with how much they weigh. Kitty is petite and she knows that petite sizes range from extra small to very very large. It's a misconception to call underweight females petite. It's about height, not weight.
I have to disagree
Petite \Pe*tite"\, a. [F., fem. of petit.]
Small, little; of a woman or girl, of small size and trim figure. or
