Even though she didn't know it, Mischa was wearing this adorable Scanlan & Theodore dress at the David Jones Summer Collection Launch in Sydney last night.
Scanlan & Theodore is an Australian designer with a boutique in Sydney. Unfortunately I have not been able to find a place to buy the designs online, but I have heard that some pieces can be found at certain Barneys and Saks Fifth Avenue stores as well as Harvey Nichols and Selfridges in London.
