Kate Middleton steps out in stunning, stylish blue gown for charity gala

The Duchess of Cambridge has done it again. To attend the SportsAid Gala Thursday night, the royal mother of George and Charlotte donned an equally royal blue gown, stealing the show in that effortless way she always does.

The shoulder cut-out dress was designed by Roland Mouret, who has designed several other knockout numbers the Duchess has worn in the past. The designer most recently outfitted Heidi Klum for the annual CFDA Fashion Awards Monday night.

The charity provides financial support and recognition to young British athletes during the early stages of their careers, and the British royal has been a patron of it since 2013.

Since having been British Vogue's cover girl in May, the Duchess has had a whirlwind of iconic fashion moments, from the recent garden party in which she dazzled in Alexander McQueen, to her chic Banana Republic skirt at an earlier public appearance and now this.
