Maisie looked all grown-up in her retro number, which featured cut-outs at the waist and crystal-embellished embroidery on the bodice.

The British beauty made a big impact on the red carpet in the ethereal outfit, which was set off with a pair of strappy nude stilettos and Monica Vinader Siren studded earrings.

She opted for a dewy make-up look with sparkling eye shadow and wore her hair in a glamorous updo.
