No, seriously. Trash and found objects!
Trish’s trademark lightning bolt bustier (totally secure without tape or glue!) was made from vinyl scrap, leftover from Mephistopheles’ wings. Lady’s greed plaid skirt was made by pleating together scraps of green fabric taken from the trash, then painting with a plaid pattern. Dante’s red coat and vest were custom made for this costume, but the sword Rebellion…. It’s trash, too.
(Why yes, we are the group which offers the No Budget, No Skills, No Problem! costuming panels and workshops — why do you ask?)
The Trish costume cost less than $10 to complete. The Lady costume cost less than $20. Dante’s was the price of fabric and our labor to sew. The handguns are designed to comply with Gen Con’s draconian weapons policy and are just paper mache L’s from Hobby Lobby, painted to resemble the individual guns in the game.
