Sienna Miller looked stunning in an asymmetric midi dress as she attended the photocall of her upcoming film “High Rise” at the San Sebastien International Film Festival in Spain on Tuesday. The festival is being held at the Kursaal Theater in Spain’s Basque Country.

The star was attending the promotion of her new flick which is slated for release later this year, alongside her co-stars Tom Hiddleston and Luke Evans. The trio were present at the festival, where “High Rise” is participating.

The stylish actress wore the latest look from Victoria Beckham’s Spring/Summer 2016 collection. The design was showcased on the fashion designer’s show at the New York Fashion Week. Miller looked effortlessly chic in the sleeveless dress that featured a plunging neckline and wrap silhouette.

The oversized gingham print added a very summery vibe to the outfit. The form-fitting number showed off Miller’s svelte figure. It also featured a very low-cut back that ran right up to her waist. The actress teamed the number with black strappy block heels.

Miller accessorized with only a delicate ear cuff. Her make up consisted of subtly-defined eyes and tinted cheeks that highlighted her complexion. Her blonde tresses, which were colored with golden highlights, were styled in tousled waves and left loose.

Miller’s appearance at the festival came just a day after she attended the Burberry show at London Fashion Week and sat front row. The “America Sniper” actress, who recently split from her long-time partner Tom Sturridge, was seated on the front row of the block Burberry Spring/Summer 2016 show along with Kate Moss, Suki Waterhouse, Cara Delevingne and her girlfriend St Vincent.

Miller stunned at the show in a collarless green fur coat which she paired with skintight black jeans and low-key ankle boots. She kept the rest of her outfit centered-around the Burberry shearling coat, which is from the British brand’s A/W 2015 collection and is made of faux fur.

She wore her new gold-tinted tresses in loose waves around her face with a centre parting. The color of her hair was in perfect contrast with her coat. She kept her make-up minimal with only slick of pink lip gloss and kohl.
