Gwyneth Paltrow was looking her best on Monday as she hosted an event promoting her skin and haircare line Goopglow in East Hampton, New York.

The 49-year-old Oscar-winning actress–turned–lifestyle products mogul glowed in a lustrous yellow satin ensemble while she was joined by several other high-profile guests, including Savannah Guthrie, Rachel Zoe, Jessica Capshaw and Jessica Seinfeld.

All eyes were on Gwyneth at the exclusive pajama party thrown by Goop and their partner Cartier to showcase the launch of the brand's new transformative overnight skincare product, the Dark Spot Exfoliating Sleep Milk.

Gwyneth's outfit looked like a comfortable set of pajamas, which she paired with a set of fuzzy yellow–green slippers.

She wore a canary yellow top, which she left unbuttoned and open, revealing her flat tummy and a matching yellow bra made of the same material. 

She stuck to the same theme with draw-string pants, and she added some sparkle with a gold chain dangling from her throat.

The Royal Tenenbaums actress wore her blond hair styled in a casual bun to put the spotlight on her impeccably made-up face, which had a youthful, natural look.

The ultimate slumber party was the Goopglow event in East Hampton, where was our invite, please Gwen?!

Of course, the hostess with the mostess was founder of the brand and actress Gwyneth Paltrow, who certainly dressed the part for the occasion! Leading the way in a sunshine-hued silk ensemble, which would not look out of place in an old Hollywood film, feathered slippers included!

Comprised of a shirt, cropped trousers and bralette, that is way too chic to wear only to bed! It hails from cult favorite brand Olivia von Halle, who we have seen on Jennifer Lopez, Kourtney Kardashian, Victoria Beckham, and Chrissy Teigen.
