The model-actress attended the Golden Globes on Sunday wearing a revealing silky yellow Reem Acra gown that included a slit up the middle and an embellished collar down her chest. Ratajkowski struck several poses during the course of the evening, and often parted the dress to reveal even more skin.
However, at Warner Bros. Pictures and InStyle's 18th Annual Post-Golden Globes Party, the 25-year-old star accidentally flashed her underwear while playing with the gown's dramatic slit. The wardrobe malfunction didn't seem to bother Ratajkowski, who posted a video and photo of her look to Instagram on Monday morning. "What an amazing night," she wrote.
Yellow gowns were a big trend at the Golden Globes. In addition to Ratajkowski, Natalie Portman, Reese Witherspoon, Maisie Williams and Kerry Washington also wore the bright color.
