Hi! And no you’re not at all :)
This is always a difficult one to answer because it always depends on the parents. My dad is in bands, so he’s always worn wacky clothes, so our family is pretty used to it. Although my mum was very strict on no hair dye and no make up, I wasn’t allowed to wear makeup until I was 16 (that doesn’t mean I didn’t put it on when I went to school and then took it off haha!).
I found the best way was to gradually change my style, with just accessories or a t shirt to start off with, and then just build it up before they suddenly find a fully blown kawaii mess in front of them haha! It got them used to it and it wasn’t such a full on shock and it helped them embrace it more.
Your parents only want the best for you and sometimes it’s a little hard to make them see that it’s only clothes, but until you’re 18 or you can move out, I don’t think there is really much you can do if they’re really strict. If you have a respectful conversation with them, maybe even show images or people that inspire you, they may respect you for that and might be able to see your side.
But anyway, stay inspired and I wish you luck! And I’m sure you look fab in whatever you wear! <3
