Guys if you're looking for a sharp look to get some sophistocated ladies, I would suggest going for the scarf look along with some khakkis. It's clean and comfy. You can also never go wrong with a trench coat.
If you're trying to go for the bad boy look (because who can resist that) I would reccomend using leather or camo with a dark wash jean. Maybe even both! Alot of black is ideal this season.
Men are also playing around with different patterns this fall. With pants to tshirts to button downs and scarves, they're showing off their funky side.
Graphic tee's will also always be in style.
