@ossobuco,
Rive Gauche is the boutique collection of YSL. Very much in these things is relative though - not everyone wearing couture has paid full price: the models' clothes, in particular, can't be used once the next collection is out, so they are given at nominal prices to people who can fit into them, which is how I ever got to own any couture. But you surprise me with the Lisa Minelli mention - the woman is very short, I wouldn't have thought she would go for Halston dresses. Still, you're right, I looked it up - obviously she did. My personal reason for wearing his dresses is that I was working at 645 Fifth Avenue at the time, and he also had his showroom in the same building, so I knew him and even though I never asked for a discount he just plain offered. Back to Boomerang's topic, Halston dresses and disco hangouts like Studio 54 were quintessentially 1970s.
