Another from the twenties or a possibly more risque set of outfits either flapper or corsets etc.
The Film Chicago

You have the female Murderesses from the song "I didn't do it"
as well as Velma Kelly and Roxie Hart
   Nickie, Liz, Annie, June, Hunyak (foriegn one), also if one of your ladies would rather take a more subdued costume gray suit would do it, there is the prison governer Matron Mama Morton. For the male there is   Billy Flynn as played by Richard Gere. or possibly Amos Hart Roxie's husband or just simply a corpse belonging to one on the women.

Only problem it gives Pixie a legitimate excuse to go around as a murdering female Oh.. Hang on. Cllr
