The Event: The Hublot & Haute Living Toast Art Basel dinner on Monday evening. The actress hosted the event, along with hubby Dwyane Wade.

Why We Dig: Between the luxe linen, long train and emerald green sash, the outfit made Union look like the goddess of chill in her regal Rosie Assoulin Resort ensemble. While the dress may not be well-suited for all occasions, it was the perfect choice for the actress' trip to Art Basel on the easy-breezy beaches of Miami. Paired with an effortless half-up, half-down do, natural makeup and elegant gold sandals, the 43-year-old's look was on point.
