Marc Jacobs designs SCRUMPTIOUS shoes. I would order 1/2 size up, depending on the style, but, ideally you should try them on, of course. I have 3 pairs in a size 41: the boots are just slightly larger than I expected, but it's ok because they're boots; the orange velvet+patent flats are just right, and these navy blue 'mouse' shoes are too narrow and a bit tight (unfortunately), so I keep trying to wear them and stretch them a bit. Um... not sure this is helpful, but if you order them without trying them on, make sure you can return or exchange them.
