Sienna Miller stunned in a flirty lemon frill dress on Wednesday at The Lost City of Z Premiere at ArcLight Hollywood.

The blonde beauty was promoting her upcoming film The Lost City of Z in Los Angeles. The 35-year-old actress, who plays the lead character’s wife Nina Fawcett, flaunted her toned legs in Chloé Ruffled Dress from the Spring 2017 Collection. She accessorized the casual, bohemian look with a sand-colored clutch from Chloé, called ‘Nile‘ Minaudière. It was a retro look that Miller is a pro at pulling off, and which she rounded off with Gianvito Rossi Sandals and Cartier Jewelry. The sandals are in actuality metallic-colored pumps that give the petite star a flattering boost as she posed for cameras on the runway. She finished off the polished look with subtle makeup that accentuated her dainty features.

Here’s a guide to achieving Miller’s romantic, effortless look.

For the flowy, springtime feel of the dress, look no farther than Jessica Howard’s Belted Floral-Print Fit & Flare Dress and Cardigan, available at Macy’s. For the earthy vibe of the clutch, go for the affordable Women’s Net Embroidery Clutch Handbag Champagne available at Target.

And don’t forget the heels! Round off the look with nude sandal stilettos by Steve Madden, called Stecy Two-Piece Sandals, available at Macy’s.
