OMG! This is such a beautiful color. Couldn't resist it after seeing the photo you posted. Just placed an order for it. Can't wait for it to arrive.I got this one as well ,the actual colour is a bit different from what you see in the official pictures (see below)..
interesting though, a younger friend of mine once commented on a YSL muse bag of similar colour as looking "too mature" for her .
Personally, I love this colour a lot. For young girls, you can wear it a something "spectecular" or "shocking"..
however, for more mature women, it's actually a very feminine choice... it add a extra dose of feminine to everything I wear
