What a lovely dress - and what a great story! I also appreciated your explanations on the autumn 1958 collection and St. Laurent.
I have this autumn 1958 German fashion magazine called "Elegante Welt" that I bought last December, and it has several photos of dresses from that collection in it, as it reports on all the trends of the autumn Paris shows of that year! This article is actually very enthusiastic about the "arc" line, calling it "giving women back their figure" after the "trapeze" line which this particular journalist obviously didn't like. ;) I can see that it is a shape that doesn't fit every woman, but I like it. I haven't been much aware of this particular trend I admit, so looking through this magazine was a bit of an eye opener, and your blog post added some info. I have been to the big St. Laurent exhibition in Montreal, but that one didn't show much from his time at Dior.
