This Fair Isle pattern cardigan from M&S brings a classic knitwear look to her wardrobe. Finished with a round neck and ribbed cuffs, it fastens neatly down the front with buttons for easy wear. A regular fit gives room to layer over shirts and t-shirts, while the added stretch means it moves with her through busy school days and playtimes alike. Easy to throw over a dress or pair with trousers, it's a cheerful layer built to last the term.
