Sara Richard is designing cosplay costumery. Or, "fashion designs inspired by pop culture."
I thinkj they're rather fun.
Such as these three examples, based on Hellboy and Abe Sapien, Back To The Future and Sailor Moon.
Traditionally cosplay comes off the rack or self designed. In recent years there has been a growth amongst those creating cosplay costumes for others, often specifically comissioned and tailored. It was only a matter of time before that started to merge with traditional fashion modes of operation..
