$20,000 This dress Nicole Richie wore for her 2010 wedding to rock star Joel Madden, was designed by Marchesa. But the dress pictured above was only one of three she wore to her wedding by the same designer. Way over the top, the bottom of the dress alone was made of more that 100 yards of silk organza tulle, shaped into beautiful petals. The top of the dress was lace and featured long sleeves. So who inspired this one of a kind stunner? None other than Princess Grace Kelly.
