Off with her feet! This thong sandal by Rene Caovilla is not dangerous by height but by its jewels. Anyone could mistake the crystals for diamonds... I mean anyone, so don't walk alone wearing this in dark alleys. Thongs as lovely as this can be worn with a formal dress... never mind if it is flat, the glittery huge crystals are enough to make it an evening shoe. You can get this at Bergdorf Goodman.
