do what you want young lady. It's your life, people who tell you what to do, is based on what they would do, this is the problem. Cause what one person considers garbage is another person's treasure. MY mum does this to me all the time I just laugh it off. It's water off a ducks back with me. Change your hair, change clothes, etc I am like whatever mother. Just ignore her. Take no notice of your mum. She is judging you based on things she doesn't like about herself. The saying goes when you judge another person you don't define them, you define yourself.

I get you and I get your mom too...
I guess your style wouldn't necessarily be considered a style per se... Since it's just some winter/skiing style clothing.
I think your mom wants you to represent your family with good style - or what she considers to be good style. If it's not your own I wouldn't do it, though. If you're going to feel uncomfortable in it - don't do it.
