I know I say this about every bag I find, but I think this really is the best high street alternative to the Chloe Silverado that I've seen. It's from Next, and at £89.99 it's not as cheap as most high street copies, but it is made from metallic snakeskin effect leather, rather than a cheap-looking pleather. For those on an even tighter budget, there's a smaller blue version for £54.99.
