Kate Hudson and her ageless mother Goldie Hawn may share flawless figures, bubbly grins and perfectly tousled blonde hair, but last night at the Elle Women in Hollywood gala, they also shared the same dress style — by accident! Hudson sported a black dress with iridescent paillettes from up-and-coming designer Prabal Gurung at the star-studded gala, while Hawn also bared a shoulder in white Gianfranco Ferré–but it wasn’t planned. “When we came in we were like, ‘Ooh,’ and we felt like a one-shoulder thing happening!” laughed Hudson. But it turns out that Hudson has another family member that she counts on for style advice — her son Ryder! “Oh my gosh, yeah. He’s my biggest critic: ‘What is that?’” said Hudson. “I always know when he likes it when he sees me and he doesn’t say anything and he gets kind of flushed. I go, ‘Oh-ho. That means you like it!’” –Scott Huver
