The men’s 20’s gangster costume lets you channel your inner Al Capone at your next fancy-dress party, stag-do or Halloween event. The roaring 20’s saw the rise of the glamourous gangster in America, largely due to the unsuccessful prohibition law that banned alcohol. Fortunately, you can still have a drink if you like in the 20’s gangster costume, which includes a pinstripe jacket with shirt and tie insert and matching pinstripe trousers.
