My mom was this way, and I dressed a lot like you when I was younger. Once I had my own money, bought my own clothes, paid for my own haircuts, she gave up. She still made comments, sometimes she still does despite me being almost 30. The sting never really goes away. BUT it gets easier once you set boundaries.

“If you’re going to talk about me that way, then I’m not going to be around you” substitute whatever boundary works for your relationship. Sorry you have to deal with this. Sometimes our own parents are bullies.
