Sculptural ruffles, plunging necklines and seemingly endless yards of tulle all earned a prominent place on the red carpet at last night’s Screen Actor’s Guild Awards, at the Shrine Auditorium in Los Angeles. (Technically, it was a silver carpet to commemorate the 25th anniversary of the awards.) Lady Gaga absolutely dominated — just as she did at the Golden Globes — in a feathery Dior Couture gown with a scandalous thigh-high slit. Also amongst our favourites: Susan Kelechi Watson in a stunning tiered tulle gown by Christian Siriano and Emily Blunt in borderline vulva-shaped custom Michael Kors.
