Am I too old for the grunge style?

I was quite a nerd in high school and a late boomer in (too) many things. When girls were chit-chatting about the new beauty guru's videos on YT, I was waiting for the Witcher game and nothing else mattered to me lol Simply said, I started to care about fashion and similar stuff much later than the others. But now I feel like this style is just for young teens (14-16) or am I wrong? I'm not sure if it's just me (I do overthink things a lot) but I feel like I'm supposed to dress different.. eh. I don't really know how to explain it better.

It's like.. I'm soon to be 19 but what I want is to dress as a 16 year old girl, the way I want because now I actually have the money, a little bit of confidence and wishes to actually buy the stuff I want.
