Perhaps the most interesting similarity I've seen recently is the Kate Spade "Wish You Were Here Coal" tote and the Summer 2010 Louis Vuitton Ailleurs collection totes. As soon as I saw it, I was strongly reminded of the Summer 2010 Vuittons. While not a simple imitation, it is very reminiscent.
As my readers may know by now, I am completely in LOVE with Louis, so I must say I'd definitely prefer the Ailleurs over the Kate Spade tote. Having recently acquired a Kate Spade iPhone and iPad case, my opinion of the KSNY brand is not a negative one, but I think the green handles and the green bottom of the Kate Spade tote lessens its "pop" and overall glamour.
Which would you choose?
