Zara Dress:
As if her high street shopping habit didn’t have us swooning over the Duchess to begin with, her knack for maximizing versatility has us even more enamoured. Kate donned a black and white circle print dress from Zara in 2007 when she spent the night bar-hopping (with sis Pippa, obvi) in London. All the Jello shot stains must have come out, because she wore it again in June 2011 to a wedding.
