Suit: Choose a two-piece suit in something wrinkle-resistant. Merino wool and high-twist yarn are good options and can carry through most seasons. Linen is a bad idea, no matter how warm your destination is.
Classy-casual sweater: Whether you’re exploring the city on a weekend, meeting for a casual bite with colleagues in the evening, or hanging out in your luxury apartment rental, you don’t want to keep that suit jacket on all the time. Choose something comfortable but classy – cashmere is always in style
Running shoes: You won’t want to neglect your workout routine, especially if you’ve had to sit on a plane for hours to get there. Pack running shoes (and a t-shirt and track pants, something quick-dry and antibacterial is the most convenient) so you can take advantage of the fitness facilities at your accommodation or even get outside for a run. Healthy body equals clear mind equals kick-ass performance in the conference room.
Reversible leather belt: Great for switching between outfits, a classy belt in both black and brown will pull your look together (and take up less space in your luggage. Try this one from Nordstrom.
The all-in one? Well, this one may be ahead of its time, but the ‘suitsy’ is the latest thing to hit men’s fashion and it could revolutionize your business travel wardrobe (then again, it could just turn out to be a novelty item you buy your brother for Christmas.) It’s comfortable, practical, and, the makers say no-one will know you’re wearing a zip-up one-piece that feels as wearable as a set of pyjamas! It’s still in the development stages but you can check it out – here.
