Size guide
Size it right
• Use our size charts for clothes, socks, shoes, mittens and hats
• For clothing, go by height and chest size, rather than age
• Measure from the top of baby’s head to the bottom of the heel (height) and under the arms at the widest point (chest)
• Check out our ‘true to size’ scale for products online, based on customer reviews

Room to grow
• Baby on the way? Don’t shop too much; you’re likely to receive gifts of clothing in the smallest size
• Keep that mindset and never buy too much in one size — babies always grow quickly!
• If in doubt, size up so that your baby can grow into it (that goes for you too, gift-givers)
• Babies grow fast, so we've made garments with 2-in-1 sizes that grow with your baby, and can be loved for longer.
