Carbon Costume

Andrea Beaumont (voiced by Dana Delany) is a character in the Batman cartoon movie Batman: Mask of the Phantasm.  The one-time fiancee of Bruce Wayne, Andrea eventually becomes the villain Phantasm.  If dressing like Andi before her descent into darkness, you’ll need a coppery wig and a sophisticated appearance.  A sunhat and white gloves paired with a chic dress will easily get the job done.  If your look aligns more with Phantasm, you’ll want to start with a black body suit and pair it with grey gloves, a mask, and a hooded cloak.  You can choose to find a replica mask, or opt for a more generic skull face covering.  Likewise, finding her scythe glove might not be possible, but you can achieve a similar look by removing the top from a costume scythe and carrying it with you between your fingers.
