I'm starting to upgrade my wardrobe. The standard advice around here is to look at /r/malefashionadvice. It seems like a lot of khakis, polos and button-downs get recommended there. I'm looking to stop looking like I work at a fast casual restaurant and put together a more alpha wardrobe.

All I can think of are outfits based on denim and t-shirts. Any help here?

Also, accessories. How important? What about watches? Do women care?

If you started out looking like a suburban Dad, how did you bring the sexy to the way you dress?
