You’re convinced that behind the threadbare boxers and piles of concert tees, there are some serious skeletons in his closet.

Help him exorcise his poorly dressed demons with shirts from Commonwealth Proper.

The debut collection of button-downs is designed locally and stitched up in nearby Newark. Alex Avendano and Craig Arthur von Schroeder have taken a painstaking approach to achieving the perfect fit by replacing the bulk with a flattering slim cut. Substantial pearl buttons, collars that lay crisp and flat, and contrasting cuff inserts make for an off-the-rack garment with a custom feel.

He may even make it onto the designers’ blog, where they promise to post pics of the most nattily dressed guys in Philly.

No bones about it.
