My friend & I recently attended a con dressed as Arkham City Harley Quinn & Arkham Asylum Poison Ivy. Both costumes were hand made by ourselves. My Harley costume was hand sewn, and took 5 months (with no slacking lol). It needs a few tweeks for the next con, but overall I was happy with the final outcome & it was a blast to wear. Unfortunately, we ran out of time the morning of the con (after 6 hrs of getting ready!) to apply all of Ivy's "puffy vines". The improvised vines are just painted on. But it was still super fun!
