Use dim lighting with candles or warm string lights to create an intimate and sophisticated atmosphere.
Encourage guests to participate by awarding prizes for the best-dressed gangster, best flapper outfit, or most creative costume. Custom invitations designed to resemble secret mafia meeting notices or vintage newspaper clippings can also build excitement before the event begins.
Adding personalised touches such as customised welcome signs, themed menus, and matching table settings will make the celebration feel polished and memorable.
