You'll go mad with glee when you put on the men's Hatter fancy-dress costume for your next event or party. Not exactly known for his stable levels of sanity, Mr Hatter is a brilliant and quirky costume idea that's especially well-suited to Wonderland themed parties or events. The men's Hatter costume is well-detailed and comes with a long jacket, waistcoat, shirt with necktie and of course an oversized hat with attached wig.
