If $3,100 could buy you a butt that looks that good
, would you spend it? Fashion fans are facing that question as Pippa Middleton's buzzed-about bridesmaid dress hits Net-a-Porter.com.
The infamous Sarah Burton for Alexander McQueen silk-crepe creation is available now
on the U.K. version of the site (shoppers in other parts of the world can call to reserve
) for a cool 1,995 British pounds – about $3,100. It's nearly identical to Middleton's gown, except it features a zipper (instead of buttons) up the back.
Though the delicately draped dress was knocked off several times over – as was Kate's
McQueen wedding gown – this is the only available version by the actual designer. Cameron Diaz
wore a similar gown
in red to the 67th annual Golden Globe Awards in December of 2010.
