What size should you get?

Sizing is generous and designed to last longer than usual baby and kids’ clothing.

If your baby is at the starting age of one of our sizes, then go for that one. If they fall in between sizes and they’re not on the small side, then go for a size above – it will still fit thanks to cuffs that keep legs from sliding down and it will last a long time.

Ribbing and waist fabrics may vary, but will always be a fab and fun combination.
