Sorry, men. You can thank Louis Vuitton for having no excuse for traveling in sweats anymore — or worse, your pajamas. The ultimate luxury travel brand has launched Tailoring, a new permanent collection designed by men's creative director Kim Jones that merges comfort and functionality with the formal suit. Single- and double-breasted jackets are lined yet lightweight, with shoulders that are structured yet flexible. Three inside pockets accommodate a boarding pass, passport, and cell phone. Pants are wrinkle-resistant while slim-fit shirts are made of super-thin blue or white chambray. Mercifully, the vest has been completely left out of the equation.
