Just wondering, has the shape on the First changed over the years? What I mean is, I know the names of some have changed like the First has been called Small, Classique, Le Dix, Lariat. But has the shape of the first changed over the years at all. Some of the older firsts look a little rounder than the new ones in stores (but i've only seen pics of older bags). Any advice would help. I'm learning!
