At Wednesday’s L.A. premiere of her new movie Mortdecai, Gwyneth Paltrow rocked a steel blue gown from Lanvin’s spring 2015 collection. A quick glance from the front would have suggested a simple column gown, but much to our delight, there was more than meets the eye. When viewed from various angles, the dress featured thigh-high slits from the side, a perfectly crafted racer back, and a waist-defining wide leather belt that added a layer of dynamic detailing. The actress paired her outfit with light blue python sandals by Lanvin and David Webb jewels. Overall, everyone’s favorite Goop-er did not fail to surprise on the carpet.
