Last night our favorite A-listers gathered to champion sartorial sustainability and celebrate H&M’s sixth Conscious Exclusive Collection at an LA dinner hosted by supermodel and spokeswoman Natalia Vodianova. The star-studded event included everyone from Hailey Baldwin to Kate Mara and their stunning ensembles reminded us that a warmer season is at hand. While Kate’s bright jacquard miniskirt and Natalia’s sparkly paillette top got our attention, what especially caught our eye was Chrissy Teigen’s thigh-high-split pants—which are becoming a staple among It girls (recently seen on Gigi Hadid). Witness all the gorgeous looks ahead.
