It will be the white shirt for Queens.
See he is wearing his off court uniform - black lacoste polo, I'm sure jeans and for that added touch of style, a black (lacoste no doubt) sweater, or is it a hoodie "fashionably" draped around the neck.
Well at least for Wimbledon he'll have to stop wearing that red shirt. Although it's been his lucky charm so I got to love that red shirt. Just PLEASE no checkerboard shirt for WImbly.
