Holiday dressing is one of the genuine pleasures of fashion and it deserves to be taken seriously as a category. The holiday wardrobe has a completely different set of requirements to everyday life. Things need to pack without destroying themselves. They need to work in heat. They need to be versatile enough to go from the beach to lunch to a slightly smarter dinner without requiring a complete outfit change every time. And they need to photograph well because holidays are extensively documented occasions. The best holiday dresses are the ones that look even better in the sunshine than they did on the website, which is a higher bar than it sounds.
