Yesterday Frank Muytjens showed J. Crew's Fall '13 for men, with an update on their classics. There were some colorful knits, solid suiting, and an awesome shiny waxed coat.
But if I had to pick one look that was my favorite, it was this denim x denim rust colored jacket and jean combo. Not the first time they've shown something like this, but I loved the color, accented with the navy coat and scarf. I think I'd wear it with a colorful tie, for some pop.
Hypebeast has all of the looks here -- it was hard to choose just one favorite, so check them out.
