I have the Muse in ivory and I adore it.
One of the things I love about YSL is that overall, it doesn't seem to be overly popular --at least it isn't here. I mean, people know about it and all, but you still don't see them on every street corner. I feel they are so beautiful, but in a more understated way if that makes since.
I think I may have to take a few photos... if you don't mind them coming from a crappy RAZR phone!
