In 2004, Sienna Miller was my style icon, and I wanted to be best friends with Matthew Williamson. It seems nothing changes. After seeing pictures of the duo together at Poppy Delevingne's wedding in Morocco, it made me want a white lace minidress like Sienna's more than anything in the world. This Free People dress ($268) will have to fill the place of the bespoke Williamson dress for now!
