Where to buy the high quality Cosplay Costume?

Time to talk about the Justice League Costume and the day at the pre-premiere!
I remember the day they announced the movie costume. I have been waiting for this for so long, and it's finally here. I've already seen the movie twice, and I'm already eager to see it again!
3 weeks before the pre-premiere I was asked by SF Studios Norge to make the  for the Marvel costumes creening. I was overly excited, but also nervous knowing how little time I had. I'm always trying to pay attention to detail, and use as much time as I need on something to make it look good. I would call myself a perfectionist, cause I tend to do details over and over until I get it the way I want it to be.
