Yes, indeed, the crease patterns show that for the shoot, Jimbo just took a brand-new shirt, removed it from the plastic wrapping, and put it on. Perhaps he had a new shirt still in wrapper. I would not be surprised if he's not being stuck by a stray straightpin, and trying to hide it.
You know, Jimbo, the sorts of 5-star hotels you normally stay in, do have room steam-irons. You have to add water and may even have to plug them into the hairdryer outlet in the bathroom.
No? Wifey do all this stuff for you, before? We expect to see a burn or two, in future.
Of course if this is a WMF photoday shoot, Jimbo wouldn't be in a hotel. And wifey no doubt kept the iron. And the rolling pin.
