Gwyneth Paltrow launched Goop's Summer season in London, and her close pal Kate Hudson came out in support. For the occasion, Gwyneth embraced prints in a sheer-sleeved Prabal Gurung minidress, then added much-needed edge via a black leather cutout belt and matching cutout sandals. On the opposite end of the spectrum, Kate stuck to solids in a white metallic A.L.C. jumpsuit and a Smythe blazer. She kept the monochromatic theme going with a white tee and white platform Casadei pumps, then added a pop of color with a bold pink lip. No two ways about it: both actresses delivered in the style department, but who's ensemble is your favorite?
