A friend, my husband and I did this costume for a Villain themed party in April. I'm on the far right.
And here's one of me alone
...I couldn't find bowler hats for a decent price but did find blue ones that had a fake flowers and a rainbow bands on them for much cheaper. I removed the band and flower and painted the hats black with acrylic paint, took about 2 coats. I used ribbon to replace the band around the hats. I had an old Fredrick's of Hollywood corset that I removed the cups from and attached suspenders I won on ebay. The button up I already had and I made the skirt from some material in my stash. I used a croquet mallet as a weapon cause I already had one from my Alice in Murderland costume.
