Clothing sizes drive me bananas! Like how more expensive brands are smaller? Sheesh!
I'm 5'5" and when I was 200 lbs I wore 16-18 pants and XL or XXL shirts--carried most of the weight in my chest, gut and butt.
I'm now 136'ish and wear 6's & 8's although I do have a size 4 skirt (but I'm think that has got to be mismarked or something) and depending on the brand, size sm or med in tops. Oh and I love that the girls have shrunk down to a b cup!!
It truly is amazing how very different people are!
