Turn your little heir into style royalty. Lisa Haynes reveals how to kit out a wardrobe worthy of a prince or princess.

Looking pretty as a princess is big business. When the Duchess of Cambridge wears an outfit there's a stampede to buy her style, and inspiration is set to continue with a new addition to the clan.

Half of UK parents (49%) admit that mini fashion icons like Harper Beckham and Suri Cruise influence how they dress their children, according to new research by Cotton USA.

The desire to find quality items for their little darlings explains why 66% of parents spend more on clothes for their children than for themselves or their partner.

Stand by for the pitter-patter of regal feet and ensure your own little heir dresses the part.
