I think Stella McCartney Kids‘ show-stopping Bonny swan dress is probably the most fabulous frock I’ve ever seen. It’s white cotton satin and tulle with silver and pink applique swans on the front and (detachable) wings on the back. Amazing for parties, festivals, bridesmaids or just glamming up at home. Once again I find myself wishing they made children’s clothes in adult sizes, although I’m not sure how suitable this would be for the school run… Available in sizes from two to fourteen years (although remember that Stella clothes come up small), it will set you back £86. An investment buy.
