Olivia Francis, founder of Hamilton and Hare, on creating a sleep shirt and trousers from cotton cashmere

This image was shot at the Chiltern Firehouse, just down the road from the Hamilton and Hare store, and Sam is wearing my favourite piece from the new collection: our cotton-cashmere pyjamas. I wanted to reinvent the classic pyjama with a more modern, versatile silhouette that didn’t need to be confined to the bedroom. You could very happily have a leisurely breakfast in these or pull them on after an evening shower.

Our design approach always starts with quality fabrics for underwear and loungewear because comfort is key. These pyjamas are made from an unusual blend of 85 per cent cotton with 15 per cent cashmere fibre, which gives an amazing buttery softness, while still feeling light and breathable so you won’t overheat.
