That was certainly what K wanted to say when he posed for the camera, while I was busy taking pics of the clothes...
"I can smile for you..."
"Tilt my head a little for effect"
"Throw in a coy smile"
"Ta-dah...my signature smile!"
It's interesting how it can be so tough during the other times to get him to look at or stay still for the camera, when he is the subject.
