The ever-glamorous Being Mary Jane star walked the red carpet in a multi-layer cobalt blue bamboo-print Prabal Gurung dress from the resort 2017 collection ($1,625; modaoperandi.com)—a decidedly un-Christmas-y piece. Union wore her straight black hair parted down the center, tucked behind each ear, and cascading down her back, artfully drawing attention to her dazzling coral, lapis, and malachite Of Rare Origin earrings ($1,120; ofrareorigin.com). To complement the summery gown, the Bring It On alum rocked a pair of strappy Stuart Weitzman sandals.
