I really find it so interesting that my first YSL is the Downtown - I have been in love with the Muse for so long and the very first bag that screamed to me "had to have" was last year's anthracite Rive Gauche...and here I am, curiously, without either of those two bags. So far I have -chocolate medium Downtown -Nadja (have to post pics) I'd love to start a serious collection. What's in yours? What would you consider the must-have pieces for today's YSL fan? I'm pretty certain that I'll end up getting a Muse, because it seems so established. But what about the Tribute, the Rive Gauche, etc...?
