Margot Robbie is all about weddings this year! After tying the knot with Tom Ackerley [1] in Australia in December, the Suicide Squad actress [2] was a part of another big day when she served as a bridesmaid [3] for her best friend Julia Koenig on May 10. Margot looked gorgeous in a silky dress and nude heels as she posed for photos and helped adjust Julia's dress and veil during the nuptials in Hawaii. While Margot posed for official photos with the bridal party, Tom, a film director [4], chatted with other guests before heading to the reception. Stunning!
