I think they look good on the right figure, it's like with skinny jeans. When you're not skinny it looks awful. When you're the right shape they look great. People just need to dress according to their own size and shape and not necessarily what looks good on other people.
I personally think they're a great example of something that everyone wears b/c they're in style, but looks terrible on most people who try to wear them. They hide the waist (making it look bigger) and show off the booty in a weird way. I've seen very few girls pull this off, and most of them would still look better in regular shorts with a crop top or something.
