In charming pastel hues, this colour block dress for girls is from Stella McCartney Kids. Lightweight and flowy for warmer days, it is made in breathable organic cotton poplin, and has easy-to-fasten poppers on the front. It has a gently shirred bodice, and side seam pockets for a relaxed style. The Stella McCartney fit can be quite small so choose a size up if you want room to grow.
