What is this dress a replica of?

I hope I'm not posting too much. xD I wanted to figure out what dress is this replicated from? I know it's from AP, I can clearly see that by looking at the print, that says "AP" all over it. XD
It looks familiar but I cant place it. I was considering getting it in pink, because I love the design but what do you all think? It's from Dear Celine. http://item.taobao.com/item.htm?id=7744052589 
I think it's probably the most well made replica I have seen in a while. :O
