Model Lara Stone tied the knot last weekend to comedian David Walliams in London.  The model bride wore a wedding gown designed by Riccardo Tisci to the wedding ceremony, and wore a Givenchy dress to the reception.  It was a double win for the house of Givenchy because Tisci is also its creative designer.  Her wedding dress was a beautiful ivory corseted piece made from silk satin.  The reception dress was a signature Givenchy number, metallic gold, short and sexy.  It showcased her gorgeous figure.  How did she score a custom dress from Riccardo Tisci you might ask?  The two are good friends.
