Give the Pants a Night Off

Wear the jacket like your blue blazer—with everything. In fact, it helps to pretend it's not white when you're getting dressed. That way, you won't hesitate, whether you're wearing it with jeans and a tie or with chinos and a tee.

A Suit—But Not All Suited Up

Strip the white suit of its costumey feel by pairing it with a tee and sneakers. Just keep the colors neutral—if you start throwing pastel shirts into the mix, you run the risk of veering into Don Johnson territory.
