Sleek silhouettes, clean lines, and a black background: those elements seemed to be the overarching requirements for Carey Mulligan as she chose her red carpet dresses over the last couple weeks. But we’re not complaining! Black is chic, elegant, and flattering, and most importantly it works for Mulligan’s look and style. To keep her fashion from becoming mundane, Mulligan made sure her multiple LBDs didn’t eventually lead to boring results. Each dress has offered a touch of something fresh and different from the last, either with an interesting detail or unique element. Her Met Ball dress success, for example, was thanks to an angularly designed black Balenciaga number boasting a safety pin brooch at the neck. The LBDs continued in Cannes, where Mulligan wore a hardware-happy Chloe frock with a couple of silver buttons and a cinched buckle. While in France, she also wore a strapless pencil midi designed by Calvin Klein to the designer’s Cannes after party that kept things especially flirty with a peplum skirt. The dress that most surprisingly worked on the actress, though? A sleek floor length maxi at the Great Gatsby Tiffany & Co. Dinner, which drew such positive attention with its cascading silhouette, it didn’t need anything else to it. Do you have a favorite piece or go-to look? How do you keep it from looking repetitive?
