In my opinion, the guys have it easy. The look includes tight jeans to the ankle, preferably showing white sock (ugg)! Then add a white tshirt and slicked hair and voila! 50's mens fashion. If you want to be uber cool, add a leather jacket.
Check out this kid rocking the black jeans with white socks showing! What were they thinking?! But the popped collar sunglasses are a nice touch.
There isn't too much deviation from the look just mentioned except these next two looks. I'd advise to stay away from these!
