This cotton rich cardigan from M&S is an easy layer for little ones who are always on the move. Floral embroidery adds a playful touch to the round neck, while long sleeves offer extra warmth for cooler days. Button fastening makes it simple to pop on and off, even when they're in a hurry to get back to playing. Soft and breathable, it's a lovely layer for nursery runs, playdates or days out with the family.
