Classic, Jennifer Aniston.

The 45-year-old actress stunned (once again) in a little black dress at the Toronto International Film Festival premiere of “Cake” on Monday, Sept. 8. Sporting her signature blond ‘do, Aniston wore a classic mini, which featured a pleated skirt and a small, sexy slit.

LBDs seem to be a staple in Ms. Aniston’s closet, and rightfully so. Justin Theroux’s fiancee really knows how to rock the chic look.

Speaking of Theroux, he was on hand for the red carpet event, and posed with his love backstage.
