8. Madonna’s Stella McCartney Dress – $80,000
For her 2000 wedding to director Guy Ritchie, Madonna wore an $80,000 dress designed by her friend Stella McCartney, who (while it can’t be verified), probably gave her a very friendly discount. This strapless dress was made of ivory colored silk. She also wore an antique lace veil and a 37 carat diamond cross necklace.
