J.Crew's summer-weight Fine-Stripe Cotton Suit consists of the Fine-Stripe Cotton Suit Jacket ($198) and Fine-Stripe Cotton Classic-Fit Suit Pant ($98). As their name implies, they feature a subtle stripe and a casual color called "faded black" (you mean grey, right?). Wear with the Secret Wash Tab-Collar Shirt ($62) and your favorite pair of white sneakers.
