One of our favourite, though hard-to-get, high street brands for children is COS. Working the same cool, contemporary aesthetic as the main women's and men's collections, the childrenswear features quirky cotton dresses, cardigans with discordant hued pockets and tactile accessories in a punchy citrusy colour palette for ages 0-6. Deliciously offbeat. You can find it on the first floor of COS's Regent Street branch, currently at up to 60 per cent off in the summer sale.
COS, 222 Regent Street, W1B 5BD (020 7478 0400/www.cosstores.com) Oxford Circus tube. Open Mon-Wed 10am-8pm, Thur 10am-9pm, Fri-Sat 10am-8pm, Sun 12noon-6pm.
