Tennis superstar Serena Williams showed up to launch of her sister's new clothing line "EleVen" wearing some cute pewter mary janes which I absolutely love. I my opinion metallics are better than neutrals because not only do they match every thing, but they're fun as well. I'm fairly certain that Serena's pair are from the ultra-luxe Miu Miu line, but you can cop a look alike pair from Baker's for $69.99.
