Absolutely, some people look great. But I think most rounder women don’t look good with the short cut. It’s hard to describe sometimes - it can vary with the exact style.
That is standard issue about everywhere, as I can tell. Seems few venture into long hair when they’re heavy and/or “old”. Somebody must’ve told them it makes them slim down or younger (maybe “Peter Pan”?) and that’s become common wisdom.
I’ve actually had people say “It’s time she got her hair cut.” Not because her current hair wasn’t pretty, but because, well.... time for her to be punished for getting older, heavier and being born short ;)
