Duchess of Cambridge Kate Middleton Wearing Self Portrait Lace Dress, Matching Gown as Paris Hilton and Tamara Ecclestone

The Duchess of Cambridge Kate Middleton wore a new brand at the premiere of "A Street Cat Name Bob." Turns out, the white lace long gown Kate Middleton wore to the London film premiere on Thursday evening was by Self Portrait.

As stated by WhatKateWore, before Duchess of Cambridge Kate Middleton attended to the red carpet premiere, she went to the Recovery Film Festival where it featured films created by former addicts and their loved ones about their journey in recovery from addiction. These films served to inspire others that there is hope and people do recover from addiction.

Afterwards, the Dutchess of Cambridge Kate Middleton arrived in the red carpet U.K. premiere "A Street Cat Name Bob" wherein the film was based on the best-seller novel written by James Bowen. She wore the gown from Self Protrait's Resort 2016 collection along with a pair of suede Gianvito Rossi heels, burgundy Mulbury clutch, and a poppy brooch. The dress featured a modest high neckline intricate lace bodice and sleeves, a grosgrain ribbon on the waist, and a long flowing pleated skirt with a prominent slit.

The emerging designer Self Portrait white lace dress doesn't stop there. Kate's $400 dress was first worn by the American socialite Paris Hilton to the amfAR Inspiration Gala in Los Angeles with dangling earrings, a jeweled headpiece, and a pair of white patent stilettos. Meanwhile, Tamara Ecclestone seemed to have worn the exact same dress in the Evening Standard photo shoot.

Of course, all of them looked equally chic and stunning.

According to Daily Mail, a Malaysian-born designer Han Chong founded the cream Self Portrait laced gown in 2013. The designer studied at an art school called Central St. Martins in London. He was ecstatic and cited that his "heart skipped a beat" after seeing Kate Middleton wore the gown with her hair down. Han posted on Instagram, "Feels so incredible, just like a dream! It's a proud moment for me as designer to find Kate Middleton in one of my designs. She's such an elegant woman and it's a dream to see. She looks incredible!" The brand's signature lace dresses has been said to be worn by a numerous A-listers including Beyonce, Chrissy Teigen, and Olivia Palermo.
