Thanks for the replies and link.
My search is mainly curiosity, I love the style from some of the older fasion photography books I've looked through.
A few years back I saw a "what are you wearing" bit in some trashy mag with some gorgeous 70's armani slacks.
I try not to dress in period costume or anything, but the pants I've worn from the 70's fit me very nicely (I have a weird body type, I look like a really tall guy from 200 years ago when the average man was 5'6").
I should also mention that a few female friends of mine have found a (really cheap) vintage women's designer clothing store and I'm a bit jealous.
