In London, it’s not quite chilly enough yet to consider wearing anything approaching outerwear. Indeed, after working in this office for an hour, just the notion of wearing something on top of a T-shirt is bringing us out in a sweat. Wear a cotton jersey, such as this grey one. It’s like a T-shirt, but with longer sleeves. Magic. And try smartening it up with a pair of brogues. It might not feel like the weather for them – brogues were invented for tramping through bogs in Scotland, after all – and none of us can move for sneakers at the moment, but if you wear them with invisible socks, you’ll feel the breeze. And it’ll allow you to break them in before inclement weather demands you wear them for more practical reasons.
