I too am looking for a past season scarf (from s/s 14) so have been searching the website too. For the 90 carrés, it seems only current season is available. I've tried searching a lot of European countries and what's on the website is the same.
Very frustrating, especially since there are lots of past season scarfs on the US site.
I'm in the exact situation!! If only the US site would ship to Europe
