Out of all the cosplay costumes at this year's San Deigo Comic-Con, this one easily takes the cake. The makeup on Lady Two-Face is flawless and the transformation between both sides of her face is shockingly awesome.
Edit: Thanks to Reddit user sweetloris, we found out who Lady Two-Face really is! Her name is Meagan Marie and according to her website, she works at Crystal Dynamics by day, reads comics at night, and runs around in costumes on the weekend. Sounds like the perfect woman... Special thanks to the Reddit community for always being so helpful!
