Mystique
You’re looking at the award-winning costume won at the San Diego Comic Con 2018. This cosplayer could be found in her Instagram handle, @magnetomystique; and it seems if your username on a social media platform matches your cosplay, then it’s sure that it’s meant for greatness. If you haven’t realized it yet, she’s wearing a lycra suit to make it seem like she’s the real-life Mystique mid-transformation. It’s exactly like the costume Jennifer Lawrence, and before her, Rebecca Romijn Stamos wears in the X-men movies.
