I saw the YSL show in Montreal on one of it's last days (or the last one? I think it was a weekend anyway). Got in early without standing in line when the museum opened, and spent half an eternity there, also going through the collections, just to see my favourite paintings there again (my language school from my first time in Montreal had been next to the museum, so this was a fave haunt for rainy after-school-afternoons). When I came back out, people were lining up all the way along the old museum building on Sherbrooke and around the next corner! Talk about lucky!
I agree, it was a lot to see and take in, but I absolutely adored it. Nothing else could have given me a better insight into what YSL was all about - of which I admit I didn't have a big idea at the time, at least not beyond the "usual" images from general fashion history books. The African collection was stunning - I'd never seen any of it before and so I found it even more breathtaking. But I loved the Spanish and Russian collections especially too. And it was so much better seeing these incredible pieces "live" than just in a book. What I loved too was that all exhibits were fully accessorized. And I could have killed for those gorgeous boots! I'm an admitted boot-fanatic and these styles were all so right up my street!
So - I can only recommend it, but make sure you have enough time!
