The men's 20's gangster costume lets you channel your inner Al Capone at your next costume party, bachelor party 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.
