Attire for flying out to Florence this week.

Polo shirts make great travel items, particularly long-sleeved under jackets. They are comfortable, cool and versatile, and navy is the smartest option. Just make sure the collar is tall enough to not slip underneath the jacket, and tuck it into tailored trousers to retain both formality and a flattering line.

I tend to neutral colours anyway, but a navy polo is best paired with a navy jacket, in this case a cashmere version from Solito in Naples. Avoid navy shirts, however – if you want something darker or non-corporate, try shades of grey.

Fresco trousers from Gieves & Hawkes, fresco being particularly good at avoiding creases when travelling. Slip-ons in hatchgrain leather from Gaziano & Girling (on the off chance you have to remove them in the airport). Weekender from Bown, with Talarico umbrealla (the week promised thunderstorms, though none emerged) and my Sac a Depeche in the other hand. Dark hank.
