Most Helpful Girl
I don't understand people who tie their sense of identity into their dress. But I do understand what it means to tie your identity to something. So why not dress?
If you really think this is an identity issue for you, then you need to explore that. Maybe you'll change and you'll like something else. I know I use to be a kid and a young teen, I tied my identity to my "scepticism". I was arrogant and unbearable. xD
But once I grew a little, I humbled myself and explored other ways of thinking and observing the world. I realised that my attitude is not my identity and that I don't need to maintain this arrogant, dismissive persona in order to feel like I am me.
The point is, you may have attached to something that is meaningless, which will cause you to miss out on something else that could have had meaning.
If it's just habit and just something you like wearing. I also see no point in not trying something new. All this just to see how you like it. If you don't, you go back to what you like. Nothing to do with her. It's not your problem if she disagrees.
It's one thing to question your sense of identity and to explore and reinvent yourself into something new you might enjoy. I suggest this you always give this a try.
It's a whole other thing to be blackmailed into wearing and doing stuff you don't like. If you can't like it, don't let her force it on you. You'll only resent her more and more as time passes. Walk away now.
