Need a mannequin you just can't find? Maybe he's 6' 6" tall, or has a large, not-so-handsome nose? You may need to have a manikin custom-made. Although it is quite pricey if you only need one, at least give yourself the opportunity to check your options... you may be pleasantly surprised.
By positioning a mannequin in a specific pose, the clothing displayed becomes more alive to the buyer, and allows them to see its full potential. And by putting it on a mannequin that closely resembles the actual wearer, it allows customers to see your product on a "real" person, rather than something you settled for because it was less expensive.
Creating a custom mannequin is a big undertaking with many rounds of approval and revision, but the process is well worth the time, trouble and expense when you have the perfect mannequin for your display.
