Dinner dates and other social events often require something a little more serious than shorts. And, despite the heat, things start to cool off after the sun goes down anyway. So you will likely need to pull on some trousers at some point. Chinos, in this case, should be your go-to. Not only are they more breathable and softer than, say, jeans, they are also more versatile and can be dressed up or down with ease. This slim-fit pair by Polo Ralph Lauren will work well with a smart shirt or, alternatively, this bright blue T-shirt. Tuck it in, if you like. But make sure you keep cool with some invisible socks. Your ankles will thank you.
