Stella McCartney’s kids' collection is imbued with the same playful chic seen in her women’s line. Colorful gems adorn the body of this midnight navy dress, which is finished off with a tulle skirt (aka a tutu) and puffed shoulders. The environmentally conscious McCartney has created a dress from luxe organic cotton that your girl will want to wear all the time. Add tomboy edge by pairing with high top sneakers or desert boots, or go for full-tilt glam with a pair of sparkly ballet flats.
