The Modern Family star joined a whole host of celebs as she stepped at the Nokia Theatre LA Live in America for the People's Choice Awards 2015.
And it's fair to say we're a little bit in love with Sarah's stunning outfit...
The starlet wore a beautiful pale blue and white dress designed by Christian Siriano, which featured a strapless top adorned with delicate beadwork and a textured miniskirt, complete with a longer sheer, bejewelled overlay.
With such a head-turning outfit the actress kept her accessories fairly simple, opting for a pair of barely-there silver sandals along with a boxy satin clutch bag.
And we noticed she was rocking a pretty fab mani too, painting her pointers a black shade covered with a shattered gold design for added wow-factor. Love it.
Sarah - who recently had blonde hair extensions fitted - wore her tresses in a sleek and straight 'do styled in a side parting, tucking the lengths behind her shoulders to reveal a pair of statement silver earrings.
She amped things up with her make-up too, working a snow queen look with a mix of silver and grey smoky eyeshadow teamed with mega-watt false lashes, all topped off with a slick of caramel lipstick.
