Baby girls blue dress and knickers by Stella McCartney Kids. This pinafore-style dress is made in a mid-wight cotton, with feint blue and white stripes. The shoulder straps cross over at the back and fasten with buttons onto the elasticated band at the top of the dress. A scattering of daisies are embroidered onto the back and front and it comes with matching knickers. The fit can be quite small, so Stella McCartney advises you to choose a size up if you want room to grow.
