Suddenly, fancy dress parties will never be the same again. For if you disguise yourself in this inspired creation, we can promise you'll be twice the man you were before. And quite possibly three times. For us bookish technical types at gadgetshop HQ, it's the opportunity to get the body we've always wanted, without resorting to expensive reverse-liposuction.With man-boobs the size of Buckinghamshire, thighs with their own postcode and a belt bigger than the one owned by the late Bernard Manning, this is a hilariously serious costume to contend with.

A costume-and-a-half to put tarts, vicars, babies and sheiks in the shade. It says konichi-wa, and make way.Turning Japanese is simplicity itself. No James Bond style makeover is required. No chest hair needs waxing, nor eyes slitting. And best of all, you can proudly remain a British citizen. All you need to do is pop on the suit, power-up the fan, zip up the costume, and hello Sumo.Now, if someone throws sand in your face, you can really throw your weight around.

Just bow low and take them out with a quick shuffle and a wobble of your mighty buttock. Marvellous.
