A Perfect Summer Dress - DVF

Forgive the killer stare (I was actually smiling in my head - what happened?) - but I think I found the perfect summer dress… Diane Von Furstenberg: you are a genius.
Now, the dress does not belong to me (see it here on Xuan, the real owner), but I am looking for a number exactly like this one - any suggestions? Also worn with the black LFB tote. Get yours here!
