This is an X-Men Evolution inspired Mystique from the shows first season. It's basically just tweaking her classic look here and there. She was made from mostly the Walgreens Mystique, Vintage Black Widow, Epic Heroes Mystique Hair, and the Skulls and skirt extension were actually from the original ML10 Mystique. I love this costume. Always have. Something about it screams that classic look, but streamlined and modern. Plus it incorporates the concept her original outfits were full body, and the bare arms/leg parts were a darker blue or black. Provided a picture of what I was basing it off for reference.

Thanks for looking!
