Pocket square enthusiasts will tell you that the major differentiator of quality lies in the edges—a good silk square, for example, will be hand-rolled with a precise number of stitches per inch and carefully finished corners. But what to do with heavier cottons that simply won't provide that gentle curl? Post-Imperial embraces the material and turns the paradigm on its head by fraying the edges to produce an organic fringe. The result is an acknowledgment that like the suit or jacket that sports it, the pocket square has a place in completely casual situations. Patterns range from conservative to a bit exotic, all highly wearable and averaging around $45.
