I place Sienna Miller in the same fashionable category with

Rachel Bilson

since they can both create outfits that include vintage and high-end luxury, and somehow make it all come together seamlessly. If I had caught a glimpse of these

Retro Super Future Basic Shades

in 'Sky,' prior to seeing them on Sienna, I wouldn't have looked twice. But, since she carries them off so well, as seen here with a sleek gray scarf, I now think I need a pair. Available in six other vibrant colors that are all hand-made in Italy, they're so wonderfully lustrous that it would be hard not to let them brighten your day.
