Clearly, I love both , but right now I think I can only afford to get one. I've loved the L'Epanoui for a long time now, but I just fell in love with the Spy a few days ago.
I had to pick the Fendi Spy, I think it's more practical/versatile. While the LV Suhali is beautiful, it seems like you would have to "dress nice" or "dress up" in order to carry that bag....can't imagine wearing that bag with some old jeans and a t-shirt. It's a very luxurious bag....but if that's you, go for it!
