Sofia Coppola in custom Azzedine Alaïa with Thomas Mars after their wedding ceremony in Bernalda.

SAYING YES TO ALAIA: Filmmaker Sofia Coppola, who sat front row at Azzedine Alaïa’s couture show last July, donned a custom-made Alaïa gown — in chiffon with a blush of lilac — for her weekend nuptials to singer Thomas Mars of the band Phoenix. Alaïa, who did not attend the ceremony, said he also created a dress for Coppola’s daughter, Romy.
