33796_in_l.jpgCasual Friday doesn't have to mean raking through the bargain bin: these jewelled thong sandals by Giuseppe Zanotti are the luxe (very luxe) way to do "casual", although at £415, you're going to need to wear them on more than just the odd Friday here and there to really get your money's worth.

These will also be great on vacation, with that oversized purple jewel allowing you to dress them up or down as desired. For that price, though, I'd be really wary about leaving them lying around on the beach while you take a dip in the sea...

Get them at Net-a-Porter
