You're invited to an evening of.. Murder Mystery at the Theatre! - Jim Nast
Theme:
Based in 1920s Art Deco era. Your character is auditioning for a part in the popular play ‘Tickle My Fancy’

Costume suggestion:
Fashion of the time for ladies was flapper dresses with uneven hemlines and low-heeled button-strap shoes, along with cloche hats and lots of jewellery.
For the men it was suave 1920s suits with a smart pair of spats, a straw Panama hat or boater, round metal-framed glasses, braces, and loafers.
Think the Great Gatsby, Boardwalk Empire and House of Eliott. (*THERE IS A TROPHY TO BE WON FOR THE BEST COSTUME!)
Can you work out whodunnit?
