What should my Halloween costume be?

I had a Halloween costume idea but my friend also had the same and she’s definitely put dibs on it. Anyway, I wanted a Halloween costume that’s edgy, hardcore yet good looking.
Like a costume with a jacket, blazer and boots, in that type of area. I had like the idea of SuckerPunch characters but I don’t do well with showing my stomach. So yeah.

Anyone can think of a character or whatever that has that type of style for Halloween?

Thanks in advance!
