Margot Robbie is used to transforming into a vast array of characters.

And last week, the Oscar-nominated actress, 33, seamlessly transitioned into the real-life role of bridesmaid, with Margot chosen to feature heavily in her best friend Britt Claxton's wedding.

Fans were quick to note that this wasn't the first time Robbie had stepped into the supporting role of bridesmaid.

In May 2017, she stood by her best friend Julia Koenig's side at her wedding in Hawaii.

Margot donned a pastel green floral dress and strappy beige sandals, just months after her own wedding to Tom Ackerley in December 2016.

Julia's wedding took place in a quaint chapel on the island of Kauai.

Two years later the actress supported good friend Anna MacKillop down the aisle to George Brya in a stunning Byron Bay ceremony. 

The Once Upon a Time in Hollywood star also gave a heartfelt speech during the reception at the northern NSW hot spot.

For the occasion, she wore a stunning a floor-length satin Bec + Bridge dress which quickly flew off shelves.

And last Friday Margot's pal Britt recruited the A-lister to join her down the aisle at the event at Burleigh Heads.

The actress dazzled in a slinky lemon slip dress - a simple and elegant style in stark contrast to the Barbie-inspired ensembles she paraded on the Barbie Movie press trail last year.

She could not wipe the smile off her face as she walked down the aisle behind the bride while carrying a bouquet of white Calla lilies.

Margot also kicked up her heels at the celebrations at Rick Shores restaurant alongside the sizeable wedding party on day two.

She slipped on a Barbie-pink mini tutu dress, heart shaped sunglasses and a sash that read 'bridesmaid' while partying into the night at a Vegas themed shindig.
