Olivia Palermo was among the star-studded guests to attend Christian Dior's show during Paris Couture Fashion Week, and for the special occasion, she chose a black leather belted peplum top by the designer, pleated navy shorts, cap-toe pumps, and a tweed chain-handle Christian Dior bag. There are two things we admire about Olivia's latest look. First, it matches black with navy for a sophisticated color pairing. We also love that Olivia tried the peplum trend but opted to take it to tough places via leather. Shop this similar faux leather peplum top by Tinsley Road ($89) to sport with navy shorts à la Olivia, or match it up with your colored denim for a pop of color.
