Kate Bosworth and boyfriend Michael Polish posed together on their way into a Mulberry dinner at Chateau Marmont in LA last night. Kate was head to toe in pieces from the luxury brand, including their army green dress and Harriet handbag. Kate and Michael laughed and smiled big as they headed inside, where they kept close while mingling with other guests. The couple split up earlier this week so that Kate could attend a Hollywood Reporter breakfast celebrating Women in Entertainment. She actually wore another look from Mulberry, which she accessorized with gems from her JewelMint line, at the event.
