My inclination is to get a double-breasted waistcoat with shawl lapels. But a linen suit seems to ask for patch pockets, which to my mind are too casual to accompany a double-breasted waistcoat. Are flap pockets a better option?
As for the fabric, Harrison's Mersolair has both cream and light gray in linen, but I was hoping for something a bit more substantial. John G. Hardy has a 13 oz. cream, but no light gray (which I slightly prefer). Any other options? W. Bill?
