However, not everybody has 150 to 200 dollars to spend on one pair of shoes. Luckaly, there are quite a lot of websites that sell lita-like shoes, one more similar to the real deal than the other. Below are two links that'll lead you to two of the best (in my opinion) lita knockoffs I could find.
First, and these I find to be the most similar to the actual Jeffrey Campbell Litas, are these shoes on Ebay. I want these sooooo bad, if only I wasn't so friggin tall -_-"
Price : € 25,00 - 31,91 dollars
Available colors : Black (wooden heel), black (black heel), taupe and apricot.
Second, are the lita's available on Urbanog.com. These look slightly less like the real thing, nevertheless it's a solid effort.
Price : varies from € 31,00 up to € 36,00 - 38 dollars up to 45 dollars
Available colors : A LOT + studded, different materials,...
