Kate Middleton spotted browsing maternity racks at high street store Topshop

Kate Middleton dazzles on the red carpet in an array of glamorous designer dresses but she is also known to like a high street bargain or two.

The Duchess of Cambridge, 31, has long championed the likes of Zara and Reiss and her outfit choices have sparked multiple sales booms.

And now, Kate Middleton, who is expecting her first child with husband Prince William in July, has hit the high street once more – this time to dress the Royal bump.

Kate Middleton was spotted browsing the maternity racks at high street store Topshop during a shopping spree in London.

A fellow shopper tweeted: “Oh Just an average day, Kate Middleton smiled at me! oh best bit… This was in Topshop! Truly Beautiful .”

Layla Maan, a Business Development Manager, said: “She really is stunning up close.

“I am still in shock! I had to sit down after.

“She was just browsing next to me and then was shortly in personal shopping area which I usually am in but they had security there.”

Kate Middleton wore her hair in a bouncy ponytail, with her trademark pearl earrings and casual black leggings.

She swapped her court shoes for flat boots and wrapped up warm with a short fur trimmed brown jacket.

In January, Kate Middleton was spotted in another high street store, Gap, on the hunt for some maternity jeans.

Happy as Kate Middleton may be to shop on the high street, Alexander McQueen’s Sarah Burton – the designer behind the duchess’s wedding gown for her 2011 nuptials – recently revealed wants to design maternity wear for Kate.

When asked if she would be making any maternity clothes for Kate Middleton, the acclaimed designer said: “I hope I will be.”
