Looking gorgeous in an (almost) all-white look, Leighton wore an Emilio Pucci mini dress with Christian Louboutin's "Tsar" pumps.

It's hard to find lower priced versions of items like those heels; the closest found were Unlisted's $49.00 Rosette-Topped Peep-toes, and RSVP's $62.10 "Corrine" heels.
