I agree that the term is overused, but that's how people think, in dichotomous terms, whatever isn't overweight has to be thin. But as you know, it's not that simple No, I'm not petite in height, I'm 5'5" (165 cm), which is right around average. I'm not sure what straight sized means, I've never heard the term before. I was definitely more "thin" when I was a kid, but never what I would call skinny. I've always had a full face, and am quite curvy and see myself as more athletic than thin.
