It goes without saying though that only some people can successfully execute this, and by "successfully execute" I mean make it look smashing. Swag is an essential element necessary to pull this off but mainly you need balls. I say this because mixing prints will draw attention your way and you have to be completely confident and comfortable with your look (as with everything else you wear really). It's all in the details!
Here are some pictures of awesome people - both men and women - with admiration-worthy balls.
