I won't lie, I'm a tall man. I'm above average height and my waist and chest size means I can wear pretty much anything I want. But like every man on earth I got short changed in other areas, for instance my brother got the good hair and the model looks but he comes up to my shoulders.
Knowing your body type is the key to dressing well no matter what you have to work with. This works the same way a curvier woman knows to cinch in her waist to create an hour-glass image. It's all about illusion...
