Sinful

when someone looks great in an outfit you would call them sinful. It's a way to compliment anyone, especially if it's someone boomers tend to hate on. This slang was made to piss off boomers and prevent them from demeaning people that dress in more alt fashions or wear "immodest" clothing as they put it.

Kerri: Yo, that outfits so sinful Fang!

Fang: Thanks! My skirt has pockets.
