Pippa Middleton out shopping

Pippa Middleton caused an online shopping frenzy this week


Pippa Middleton proves the 'Kate effect' isn't confined to her Royal sister the Duchess of Cambridge, as she sparked an online frenzy this week after people hurried to purchase pieces she'd been seen wearing.

The 30-year-old was spotted wearing a relaxed outfit of a navy and white striped sweater and skinny black jeans while out on a shopping trip in London recently. But it was the pair of boots by Seven Boot Lane and an Aspinal tote that Pippa had been photographed in twice in two weeks that caught the public's eye.

After pictures emerged of Pippa wearing the chic, yet casual, pieces, they sold out online in just 12 hours. It just goes to show that Kate Middleton isn't the only Middleton sister that holds sway over our shopping habits.

And it seems people are willing to pay to tap into Pippa Middleton's Sloaney style, with the Aspinal tote costing a cool £750.

The boots, from a small label started in Somerset in just 2012, are a more reasonable £150, making it easier for Pippa fans to channel the party planner's look.

However, given their popularity, you'll have to look hard and fast to get your hands on them.
