Williams, who's long been known for her cropped, bleach 'do, didn't stray far from her boho chic style. The 36-year-old actress paired a strapless lace Louis Vuitton gown with a black ribbon choker and white envelope clutch.
Wiig was also rocking her short locks, which she debuted on Saturday Night Live last November, as well as a white lacy number, although her Reem Acra gown was much sheerer than Williams' frock.
Williams was nominated for her supporting role in Manchester by the Sea, but lost out to Viola Davis. Nonetheless, she still seemed to have a great time at the Golden Globes, attending with her BFF and frequent red carpet date, Busy Philipps. The Dawson's Creek alums didn't even change out of their red carpet ensembles when they indulged in bowls of pasta after the ceremony.
