Marceline or “Marcy” holds up well for being 1000 years old! This is what happens when a vampire-demon and a human procreate: a mischievous, fashionable vampire queen who drinks the color red!? And loves to rock out on the guitar of course.
Marcy’s look is fairly simple and you probably have some of these staples already. You need the brown riding boots. I am sure you have jeans. You’ll need to get the cute grey top and Marceline’s black wig. Any grey body paint completes the look.
