I've been personally waiting for this portrait t-shirt to arrive in my local Burberry store (it hasn't yet) and now you can see a few celebs wearing it with their own personal style. The blazer look is probably the easiest to do if it's slim fitted and neutral in colour (worn by Penn Bagdley and Aaron Paul). As I've discussed before a vintage-y design (if clean) can look pretty great with a jacket or blazer and still be smart.
Nathan Followill from Kings of Leon wore it in white with what I believe is a Burberry snood/scarf executed perfectly in his own rocker style. The roll up, whether unintentional or not is one of the tiny details you can add to your Tshirt-look. You can also fold up the sleeves twice (think James Dean short from back yonder)
