Well, not exact matches this time, they're becoming harder to find
So this time, it's just about the prints
(from DvF of course)
DvF - Fall 2003
DvF - Fall 2005
Tiffany & Co - Elsa Peretti - Open Heart pendant
I'm not sure it's the medium size, I have nothing to compare with. If some of you really want to know, I guess I can sacrifice myself and go to Tiffany to check 
And Ele, about the 4.22 outfit, I have some guesses about one part of the outfit, but I have nothing final. Are you interested ?
And I have posted the DvF part of the OP on the DVF fan page wall on Facebook (I was tired of not seeing Lauren there
), so girls (I say girls because, it's a girl thing to be a fan of DvF
), you're welcome to post feedbacks about Lauren there
