You have white pants. You like them. You want to wear them. But you don’t want to look like Biff, just off the yacht.
How do you tone them down for work?
First, the don’ts: Unless you’re going for the Captain Stubing / Good Humor look, do not not wear a white shirt. Ditto white shoes.
Now, the dos: Try a lightweight chambray shirt, like this one. It's the modern interpretation of work wear from J. Crew. With a tone-matched T-shirt underneath, this breathable, chambray will soften the white slacks (and look great with jeans).
Pair it all with some casual, worn-in looking shoes, maybe roll up the trousers a turn, toss on a blue blazer, and you’re ready for the desk, rather than the deck.
