Prohibition

It's all back to the 1920s for this massive Prohibition era-themed party, boasting jazz bands, tap and Charleston dancers, gambling tables, silent movie screenings and a piano bar. Though, it wouldn't be anything without its fabulously dressed crowd, so do make an effort for the occasion. DC: Stylish 1920s essential (think flapper dresses, feathered headbands, tuxedos, top hats and spats).
