Mistress Quinzel, Steffy, Harley -- these are just some of the names that this cosplayer uses. But whatever you want to call her, can we just all agree to call her ridiculously hot?

She's dressed as Harley Quinn, her cosplay pseudonym's namesake, and makes us incredibly jealous of the Clown Prince of Crime.

This is one Harley that we'd love to take for a ride. [Calm down, John. — Ed.]

In fact, we loved her so much that we featured her Arkham Asylum Harley as a Cosplay of the Day!
