Pippa Middleton Feels The Duchess Kate Effect As Her Off-Duty Outfit Completely Sells Out

The Kate Middleton effect strikes again, but this time all eyes are on Pippa's designer outfit...

Pippa Middleton's off-duty style is proving to be every bit as popular as the Duchess of Cambridge's wardrobe, with her latest look selling out online.

Feeling the full force of the 'Kate Middleton effect', Pippa sent the internet into overdrive yesterday after shoppers splurged on her designer outfit. 

Spotted shopping in London, Pippa Middleton braved the British chill as she stepped out sans winter coat. But all eyes were on her Aspinal Marylebone Tote, which she teamed with a stripy knit.

Despite the two-tone handbag costing £795, the Aspinal of London website received a surge in traffic after Pippa's outing. The designer arm-candy is now showing 'Out of stock' online, although still available in other AW13 colour-ways. 

Somerset-based brand, Seven Boot Lane, also saw a huge jump in sales – with Pippa's £150 Alice boots now sold out. Some websites have listed 31 January as the back in stock date for the gorgeous grey suede boots, so keep your eyes peeled.

There's just no underestimating the power of the Kate Middleton effect, even when Pippa is the subject of style envy.
