From the book: “Gentlemen artists of the Victorian era would paint in very formal attire, often sporting three-piece suits in the heat of the day! This design is based on the fitted waistcoats popular during that time. Its embroidered back, which is created using the Swiss darning technique, mimics the woven pinstripe fabric that likely would have been used to create the original garments.”
