Size Guide

All sizes are UK sizes. Measure over underwear with a soft tape and compare with the charts below. If you are between sizes, choose the larger size for nightwear, loungewear and dressing gowns.

Each brand fits slightly differently. Where a product description gives the brand's own size chart, follow that one. Not sure? Email hello@cosycart.co.uk and we'll help, and remember you have easy 14-day returns.

Waist: around your natural waistline, the narrowest part.
Hips: around the fullest part of the hips.
Children and babies: height is the most reliable guide; size up if they are growing quickly.
