Cosplay!!

Ok so I got my hair done(i might post a pic of it if i can figure out how lol) and I'm going to an anime convention soon but the only problem is, is that my hair doesn't really match any of my cosplays. 

The only two I wanna wear/ have in mind is:

Nikolai: bc he has white hair and i think it might match my hair.

Hua cheng: bc he's a baddie and i like cosplaying him.

I have a lot of other cosplays but i dont think theyll look good😭.  It's only for a day, bc im going to another one soon for way longer but like this is stressing me out bc I wanna wear a good cosplay to the event.
