Your jackets spend more time on the hanger than they do on your shoulders. Investing in a good hanger will save you in the long run from puckered shoulders and deformed padding. A proper suit hanger is used to hang matching jacket and trouser sets. The hanger should offer opulent support to protect the delicate, tailored shoulder construction and drape. They should be fully contoured and have a large shoulder flare to optimize shoulder support. The trouser bar should be flocked or felted in order to prevent the creasing that ordinary locking bars can cause. The width is also important; in order to offer optimal support, the suit hanger should extend up to but not beyond the point where the shoulder meets the sleeve. This is especially important for gentlemen with broad shoulders, as the weight of a large jacket distributed on a skinny hanger will almost immediately destroy its drape.
