Silk is the earth’s strongest naturally occurring fiber, and the most widely chosen fabric for ties and pocket squares. It is largely wrinkle-resistant, with a nice, soft drape in a weight that keeps you comfortable year round. Our silk hails exclusively from Como, in Northern Italy, where silkworms nest in the region’s abundant mulberry trees. (Which is why this region has been a silk-production powerhouse since the 15th century.) This open grenadine weave, invented in the 18th century, is now largely used to add texture to ties, bowties, and pocket squares.
