Gabi Grecko on a trip to Sydney

Model/DJ Gabi Grecko and her 71 year old boyfriend Geoffrey Edelstein had an extremely busy trip to Sydney.  The highlight had to be the radio interview they did, where Gabi admitted to smoking weed.  She looked amazing in this dress though.  Does anyone know if it is an authentic Herve Leger, or some other type of bodycon dress?
