Lord and Lady Gruesome Ghoul Couples Costume
This "Lady Gruesome" costume transforms you into a ghoul or zombie (depending on how you craft your appearance and apply your makeup). The lady wears a tattered headpiece and dress. You'll have to come up with shoes and accessories yourself. Also sold on Amazon.
If you choose to wear these costumes as part of a couple costume, you'll have fun making up the backstory explaining how the Lord and Lady Gruesome became ghouls!
