Sienna Miller Was This Week’s Best Dressed Star

Sienna Miller had us all happy that summer is sticking around for another month after she wore this light and breezy floral dress by Dolce & Gabbana to launch the new BMW i3 in London on Monday. The look was so perfect that even I considered buying a BMW, even though I am clearly a gay man who clearly cannot afford to buy a BMW (or, let’s be honest, anything).

Anyway, it was hard for Hollywood to top such a wonderful dress — but everyone certainly tried. Check out great looks from Heidi Klum, Amanda Seyfried and more in this week’s best-dressed roundup.
