Mjmj Marc Jacobs Mary Janes. We must confess to having a little bit of trouble with these. The first ones to crop up were sequinned, and though they look great in magazines and on models, in real life we fear the Wizard of Oz / Minnie Mouse jokes would get us down. This cracked silver leather and satin version are a much better bet if you want to give this trend a go. We can't help wondering if everyone would be so excited if they weren't Marc Jacobs, though?
