Mary-Kate @ "Weeds" Premiere

Mary-Kate Olsen pairs her simple white American Apparel tee with a floor-grazing Azzedine Alaia skirt at the Season 3 premiere of Showtime’s Weeds at Hollywood’s ArcLight Theatre on Wednesday.

The one-half of the famed Olsen twins wore her braided hair in a Dutch crown and fittingly accessorized with a cross pendant neck (her character in the show will always wear a cross), Balenciaga shoes and a Muse bag from YSL.

Mary-Kate will play “good Christian girl” Tara Lindman, Silas’ (played by Hunter Parrish) new love interest who gets high every now and then.
