Life's little luxuries: Stella McCartney coat

Bryce coat, €1,140, Stella McCartney, Brown Thomas

This wool-blend coat isn't cheap, but if you were only to buy one thing all season, this Stella McCartney number has the ability to make an entire wardrobe look better.

The classic men's-style Bryce coat in navy, is influenced by Stella's time spent working at Savile Row, and it's the kind of thing that will never go out of fashion.
