Pale chinos are really only for the summer, at an event when shorts would be too casual. They're the kind of thing you wear to a garden party. Only ever wear them with brown shoes, a brown belt, and a tucked in shirt or polo shirt at a push. A plain smart sweater also looks acceptable. They're kind of restrictive I guess.
Shirt - (pink or blue) and sports jacket (preferably one with reinforced elbow patches) Brown shoes - broagues maybe? That's my standard way of dressing myself but I'm not exactly known for my sense of fashion.
