Hi! Sorry for the late reply, seems none of the other founders have been all that active atm.
When I picked my first cosplay I did a character I suited and that I really like. Always pick a character you like, in the end it doesn't matter if you're perfectly suited for them because it's just for fun! First cosplays though, always pick something easy
I hope this helps!! Just watch all the anime and movies/Read manga and books etc you like until you find someone that stands out and you go "Hey. I wanna cosplay that." That's what I do
