This is a great take on Harley Quinn, (from harlequin) the great Batman & Suicide Squad villainess. This will be a top look this Halloween. I love the hammer and she definitely captures the spirit of the character in one pose.
This costume is custom-made (or at least put together from several purchases). See the broach on the necklace, the goggles, hair/makeup, hammer…I think the dress too.
