There's only so much you can do to make a standard court shoe more interesting, but I think Oasis have done a pretty good job with their 'Conchita' court, which comes in tan and black. The curved vamp and half d'orsay style of the front of the shoe makes it sweet-but-sexy, while the bow on the back manages to look cute without being too fussy. These are £50, and would be good work shoes, which will also scrub up for an evening out.
