Duchess Catherine dazzles in a recycled Alexander McQueen gown for the 2020 BAFTAs

Taking note of the event's sustainability fashion guide, the future Queen re-wore a dress from 2012 by one of her all-time favourite designers.

For the fourth year in a row, the Duchess of Cambridge looked every part the princess she is as she walked the red carpet for the prestigious British Academy Film and Television Awards at London's Royal Albert Hall with the Duke of Cambridge.

For Sunday's event, now in its 73rd year, attendees were encouraged to incorporate a message of sustainability into their fashion choices, for example, re-wearing, renting or buying vintage for the special occasion.
Of course, as strong advocates of sustainability and climate change action it's no surprise the Cambridges were more than happy to follow the guidelines with Duchess Catherine re-wearing a gorgeous white and gold-sequin detailed gown by one of her favourite designers (and wedding dress designer) Alexander McQueen.

First worn during a royal tour to Malaysia in 2012, this time around the royal mum-of-three opted for a chic up-do and accessorised with gold Jimmy Choo heels and Van Cleef and Arpels earrings and necklace worth more than NZD$23,200.
This year marks Prince William's 10th anniversary as president of BAFTA and he dressed the part in a smart black tuxedo, crisp white shirt and black bow tie.
The sustainability guidelines are part of the academy's plans for their first-ever carbon neutral awards ceremony explaining in a statement, "Sustainability is very important to BAFTA, and we're doing more than ever before. The goal is that the EE British Academy Film Awards 2020 will be carbon neutral, working towards having a net positive impact on the environment."

Last year Duchess Catherine stunned at the BAFTAs in an all-white, one-shoulder gown by – you guessed it – Alexander McQueen.
The dress featured a floral motif on the shoulder, with a floaty floor-length skirt. The future Queen also paid a special tribute to her late mother-in-law Princess Diana, wearing the same pearl-detail earrings Diana had worn to a 1991 event at the same venue.

The 38-year-old had a busy week last week as she continued her work in highlighting the importance of supporting early childhood development.
The mother of Prince George, 6, Princess Charlotte, 4, and Prince Louis, 1, visited a kindergarten last week where she surprised pre-schoolers and their parents with breakfast and spoke about the landmark survey she launched called 5 Big Questions.
The survey aims to spark a UK-wide conversation about early childhood development and give everyone a say on how they want to raise the next generation. During her visit to LEYF Stockwell Gardens Nursery & Pre-School in London she was also excited to reveal more than 100,000 people had already completed the survey, less than a week since its launch.
