Kate Middleton browses high street stores for maternity wear

Despite having the world's top designers chomping at the bit to dress the royal baby bump, down-to-earth Kate Middleton has been spotted browsing the maternity wear department in Peter Jones.

Five-months-pregnant Kate was seen in the Sloane Square store on Wednesday, checking out the Seraphine maternity concession.

An onlooker claims a £39 Brooke Butterfly sleeve dress from the range caught the eye of the Royal mum-to-be.

Kate is known for her love of combining high street finds with high-end designer labels – just last week she caused a stir in TopShop when she was spotted perusing the rails by fellow shoppers, and on her recent 'Royal Away Day' engagement in Grimsby, she sported a dress from high street retailer Phase Eight and a coat from Hobbs.

Seraphine maternity wear has been popular with other famous mums, including Kate Hudson, Halle Berry and Emma Bunton.
