It would be too big a blow to their narcissistic egos to try to be attractive and fail, which deep down they know is a fact, so they lean into being ugly like it's their choice and also some kind of revolutionary act. Literally all you have to do is not be fat. Anyone with a decent body is a baseline 6/10 even with a super unfortunate face. A good looking person can wear the shittiest clothes and still look good. A thin woman dressed like this would still be ridiculous, but she at least wouldn't be nauseating.
