After a decidedly disappointing spring, warmer days – and nights – are on the way. As well as digging out your favourite sunnies and packing away your heavy duvet, it’s time to swap your snuggly pyjamas for something a little lighter.

Sleep experts agree that keeping cool is essential if you want to get a good night’s rest, and a two-piece shorts set or PJ playsuit is the most stylish way to make sure you don’t overheat during the hotter months.

This season, we’re spoilt for choice in the sleepwear department. Take your pick of touchable fabrics, from ultra-soft jersey to crisp cotton and silky satin.

Keep it classic with slouchy separates in muted colours, or jazz it up with animal prints and floral patterns. Lace inserts and ruffles add a seductive edge to camis and crop tops.
