Instead of choosing a fancy designer frock for the Macmillan De'Longhi Art Auction on Monday (23 September), Laura opted for a maxi dress by Zara.
The gorgeous lingerie-style dress featured a subtle tartan print, lace detailing and a side slit for added va-va-voom.
But although Laura's purchase came from the high street, it's still slightly out of our budget at £109. Boo!
She completed her vampy look with statement strappy heels and a tousled no-fuss mane.
Laura wasn't the only one rocking Zara at the event - we also spotted Katherine Jenkins wearing a chic animal print skirt, £35.99.
Good work, ladies!
