20's Gangster Pinstripe Costume

Our 20's gangster pinstripe costume is a proper three-piece suit: a single-breasted jacket, a single-breasted five-button vest and flat-front trousers, all in black with fine white chalk-style stripes. Wear all three for the full Prohibition-era look, or hang up the jacket once the dancing starts.

Why a Black Pinstripe Costume Reads as 1920s Gangster

Black with white pinstripes is the most graphic version of the look: the stripes lengthen the frame, and the dark base stays sharp in party photos. A buttoned vest under a single-breasted jacket gives the layered silhouette people associate with 1920s mobsters, while flat-front trousers keep the line clean down to the shoe.

Completing the Gangster Pinstripe Costume

The shirt, tie and pocket square in our photos are styling ideas and are not included. We suggest a white or pale gray shirt, a wide tie in red or charcoal, black-and-white spectator shoes and a black fedora with a contrasting band. A pocket watch chain across the vest is a good finishing detail. More looks are in our gangster costumes.

Pinstripe Gangster Costume FAQ

How do I find my jacket size?

Measure your chest at its fullest point. The chart runs from XS, with a 37.8 in (96 cm) chest and a US 34 jacket, to 5XL, with a 50.4 in (128 cm) chest and a US 50 jacket. Trouser waists run from about 30.3 in (77 cm) to 45.7 in (116 cm).

Does it work for a wedding as well as a costume party?

Yes. Without the gangster props, a black pinstripe three-piece passes as a sharp suit for an evening wedding or a 1920s-themed reception.

What should my partner wear alongside it?

A black or red fringe flapper dress with a feather headband matches the contrast of black and white stripes.
