The clocks go back this month, and with them goes any pretence that it's still summer. That makes now the right time to start plotting an escape to somewhere warmer: a week of late sun in the Canaries, a long-haul dash to the Caribbean, or a city break somewhere the terraces stay open well past October. Wherever you're heading, pack Charles Tyrwhitt's Pure Linen Shirt first.

It's one of the brand's bestsellers, and it's as comfortable on a London terrace as it is at a beach bar. Linen is the obvious fabric for hot weather. It's light, it breathes, and it doesn't cling when the temperature climbs, and anything heavier starts to feel like a punishment.

It's also easy to dress up or down. Wear it open over a T-shirt by the pool, with linen chinos or shorts for a lunch that runs into dinner, or buttoned up under a jacket when the evening calls for something smarter. It comes in a broad range of colours, so choosing is the hardest part, though there's a decent argument for packing more than one.

The Pure Linen Shirt is only the start. Tyrwhitt likes the fabric enough to have built a whole collection around it, in 100% linen and linen blends, across shirts, polos, trousers and tailoring. The Collarless Pure Linen Shirt gives a more relaxed look, and the Non-Iron Cotton Linen Shirt is for anyone whose suitcase isn't kind to their clothes. Linen Cotton Chinos cover the bottom half, and full linen suits handle weddings, smart dinners and anything else that needs a jacket. Between them, that's a whole holiday wardrobe.
