Union showed up at The Birth of a Nation‘s premiere in a whimsical white Rodarte gown. The romantic number featured a corset-like bodice, a sheer yoke, a thigh-high slit and tulle embellishments. Union was styled by Thomas Christos.

“Magical night at the LA premiere of #TheBirthOfANation … @rodarte ❤ @larryjarahsims @fionastiles @thomaschristos @isastitches Thank you!!!” Union captioned a picture of her red carpet look.

Union’s hairstyle for the premiere was almost as eye-catching as her dress. “It was different, and I wanted to emerge a little different,” Union told People. “This movie changed me.”

Larry Simms created the new hair look for Union, and Fiona Stiles did the actress’s makeup.

Union stars in The Birth of a Nation alongside writer-director Nate Parker, Aja Naomi King and Armie Hammer.

The Birth of a Nation will open in theaters Oct. 7.
