I have a pair of shoes from Office, which I love. They are simple, canvas mary jane pumps with black polka dots. Unfortunately, they are in very bad shape; I have checked and Office doesn't do canvas ones any more, only jersey, which I don't like. I trawled the internet for some similar shoes with no luck, but did find some plain hessian ones in Tesco.
I picked them up yesterday and while the quality is nowhere near that of my originals (not surprising, as they were less than half the price!), they are comfortable. They did need a bit of work to make them look like more than £8 shoes, but 10 buttons and some thread later, I am very pleased with the result.
