I think you've got to use the tux, and then elaborate with a false mustache and maybe a monocle if you can find one. A cigar as a prop might also be good.

(PS. Maybe you could even get a chocolate cigar, or a box of them, and pass them around as part of your persona.)

Lab tech: lab coat, goggles, clip-on ID, test tube shooters of vodka and whiskey.

Criminal: black pants, striped shirt, strip of black cloth across the eyes, black beret. Knapsack optional.

Chalk outline: ninja costume, chalk. Numbered flags sticking out of random places and a blood stain encouraged. Bring chalk with you so people can make their own notes.

Count Chocula or Corporal Brown.

Personally, i think you should find a distinguished men's hat and a nice suit of the stylish forties look, pencil on a thin mustache just above the lip, gloves, cane, and a smarmy sneer that thinks it's a sincere smile. Shoddy shoes and moths that escape your pockets will help make you look suspicious.

I ended up wearing a regular suit and a trenchcoat and going as Detective Mike Logan (not that anyone in the UK knows who he is). I made a fake NYPD badge and brought a big Zip-Loc bag marked "evidence" and a reporter's notebook. It was a big hit.

As a bonus, the props made it really easy to chat people up.

Also, chocolate.
