General Quarters makes these "Wave Kerchiefs" that are available at Archival Clothing. To be more specific, the "wave" is a traditional Japanese pattern that in this case is discharge printed on 100% cotton blanks. Handkerchiefs are seriously underutilized by society. You can artfully drape and stuff them in all sorts of pockets for an expensive affectation. You can even use expensive handkerchiefs to wrap an even more expensive gift to create a turducken of gaucheness. What you can’t do is blow your nose in and/or on these. Not only is that wildly unsanitary, but, let's get real, you’re not paying $22 bucks to deal with high pollen counts.
