I puzzled about how to get the Harley Quinn one-piece look with two pieces. The bodice reverses the legging colors, but the color change needs to occur higher than the top's hem. Some online costumes reversed the colors in two places: below the bust (empire) and again at the hem of the top. I wanted one sweep of color from the empire line to the bottom of the legging.
This top is built to last and is now a part of her everyday wardrobe.
BTW, this is my 30th rendition of Kwik Sew 2555 since I started tracking my pattern use.
