Are you sure the black and white dress isn't 60's fashion and not 70's? 70's was more brown and orange, tank tops, long collars and pointy cuffs. Or there is the other end of the 70's - punk.
i had a black and white dress in the 70s from dotty p's it was a shift dress with a tie belt and elbow length sleeves. the beatnik dresses the mods wore were bold black and white and geometrical patterns
tons of make up. lots of white shiny stuff thick as anything on the cheekbones and eyebrows (as dot says)...stick on starts etc on the face. dont forget the farah fawcett hair do!
