Our spring comes earlier than some, and by evening yesterday the temperature was perfect for a topcoat. As you know, topcoats are not as warm as overcoats. They are made from lighter cloth than their winter counter-parts, and are typically shorter which incidently lets them better accommodate autombile travel (and why has no-one built coat storage into autombiles, I ask - but that is for another time). And they are ideally tweed. The topcoats that is, not the automobiles.
What tweed provides us besides water shedding properties and warmth is a wide variety of patterns, and the illustration shows a couple of nicely bold choices. I believe that at least one coat in every man's wardrobe should be something other than a solid. Keep your solid colored cashmeres and vicunas (well, perhaps you could send me the vicunas). Wear a patterned coat in Spring.
