Male mannequins, like their female counterparts, are used in many ways by retailers for display.Male manikin are seen as headless in designer windows more often than their female counterparts.
Some people speculate that the headless male mannequin is more effective because men don't want to "identify" with the model the way that women want to imagine them as the model when looking at clothes.
Similar to female mannequins, they are idealized in body type, usually with well defined muscles analogous with the ultra thin and tall female models.
