Every Sunday, we feature a square from our Put This On shop. This one is a gorgeous navy, and it’s perfect for enlivening a summer suit without shouting too loud. The fabric is an exceptionally fine cotton – you’ll have to feel it to believe it. As always, it’s hand-made in our atelier here in the US of A, and as always, by offering it directly to you you’ll save about 40% off the retail price. You can buy yours now.
