Popular costumes at the cosplay convention included die-hard Marvel and DC comic book fans dressed in iconic characters from Catwoman to Batman to Deadpool and Emma Frost from X-Men. Ideally, you’ll find a website that offers the same costume that’s cheaper, uses better materials and has more accessories included with the cosplay (e.g. wig, necklace, gloves). Conventions are hot, no matter what season, and you will be inside in close proximity with people, so consider the fabrics and accessories of the costume to portray your character.
