Husky Wear What Should I Wear To A Murder Mystery Party?

What should I wear to a murder mystery party? - husky wear

If in 1942 with headquarters in France, and I am a French woman in my 20 years. I'm a cabaret singer's hoarse voice, sensual, decadent, exotic, almost androgyenous.
The clothing is cut a dark suit with a male.
Please help me, because I do not know what they wear, and I have a costume:)
