To celebrate the opening of the Fashion on the Ration at Imperial War Museum London, we’re offering five lucky winners the chance to win a pair of tickets to enjoy a vintage day out visiting this fascinating new exhibition, followed by cocktails and a sharing platter at Dirty Martini.

Marking the 70th anniversary of the end of WWII, Fashion on the Ration (5 March-31 August) looks at how fashion survived and even flourished under the strict rules of rationing in 1940s Britain, often in new and unexpected ways. The exhibition explores how men and women found new ways to dress as the rationing of clothes took hold, revealing what life was really like on the home front in wartime Britain.

Following your visit to the exhibition, you’ll get two cocktails and a sharing platter at Dirty Martini, the cocktail bar with the perfect mix of spirit and sophistication. With a bespoke range of Martinis and signature cocktails, this is the perfect destination to round off a day celebrating sophistication and style.
