I sooo don't like the New 52 Harley Quinn, but that is a fantastic cosplay of her, and makes her about a million times cooler and awesome.
The dye job on that Ivy is whoa *-*. I've considered making that costume, and researched, and I bow down to her for achieving it.
And your silhouette as Catwoman *-* holy cow. Beautiful sleek lines and perfect make up and hood shape.
