Yesterday in London at the Glamour Women of the Year Awards, the actress debuted a red carpet pajama look, joining the comfy (and daring) ranks of Marc Jacobs, Rihanna, Sofia Coppola, and more. Jones picked out a navy floral-print ensemble from Erdem's pre-fall collection and strutted down the carpet and stage in this casual-cool look to pick up her Filmmaker Prize. She made her outfit nighttime (but not bedtime) appropriate by swiping a bold red onto her lips and wearing black-and-gold kitten heels. Serious question, though: Are red-carpet pajamas too nice to actually wear to bed? Because while the top is loose and light, those trousers look way fitted.
