Here is a dress that had us trying to identify the style from grainy paparazzi type photos. The popular blog at amalalamuddinstyle.wordpress.com came up with the ID for the dress so we did not have to wonder for long. Amal and George Clooney PDA at Villa d'Este: Amal Clooney wore a romantic lace Stella McCartney dress accessorized with matching drop earrings. I could not find a picture of the exact dress so I created this picture by using photoshop to colorize the white lace of another version of the dress:

Dress like Amal for a romantic evening with a sheer coral/orange lace maxi dress to show off your summer tan.
