Heidi Klum was decked out in purple last night for a bash celebrating the release of designer Roland Mouret's new collection, the the RM by Roland Mouret Rainbow Project, for Net-A-Porter. A few of his brightly colored party frocks were on display, including a yellow number on Devon Aoki and a navy dress on Olivia Wilde. Rachel Zoe kept things a little simpler in a dark tone, as did Roland's fellow clothing creator Amber Valletta. Heidi's right back in the thick of the fashion world following a little time off with her new daughter Lou, continuing to look gorgeous whether it's mingling with fellow models or getting down to work.
