For this Spring Summer there's nothing more elegant and simple than what is worn by David Beckham below. Photographed in the summer of 2005 alongside his wife, Beckham is wearing what appears to be a silk shirt (not polyester!), a pair of cufflinks, a nice gold watch, a leather belt, and some dark pants. An outfit appropiate for an elegant summer dinner or going to a nice bar and club.
What I most like of it is the color and "shine" of his shirt and that he used cufflinks to accesorize. I'd remove the sunglasses since it's already dark, but they would be appropiate for this outfit in daylight. This summer the XL 70s shades are back for us men.
