oh also, are you measuring your high hip? because the correct way to measure hips are around the widest part of your butt to the front. Not even runway model's measurements have hips that small, just a thought :)
lol, you dont sound fat to me at all, but i know it is meaningless when people say that to me, so without further ado
height: 5'4" bust: (always have trouble with this, because i get 29" when i measure? but i don't think that's a size? i wear a 32 bra though) waist: 22" hips: 32" thighs: 18"
hope that helps? haha, i'm not sure what correct proportion of thighs to hips/waist is, but mine are a bit large for my size, too. it's seriously weird, cause i'm a pear shape in that my upper body stays way slimmer than my lower body at all weights, unless you include hips and ass in 'lower body' (because i have small hips and no ass, haha)
All of you sound like your thighs are thin in a healthy NON pear shaped way. I am 5'9 and at my lowest weight (125) have thighs that are about 18.5 inches and they look way too thin. Since you are a little shorter they must look perfect. Relax
