I suspect that they must have done this with BBC approval to be able to use the Sherlock name the way they have. I suppose, since Belstaff aren't making the coat anymore (at least at the moment) and because it was so expensive to start with (£1,300+) that this is a more affordable version for people who might want this version. It looks like a pretty much classic trench/greatcoat.

BBC don't own the name Sherlock & there is no advertising to suggest anything to do with the show. So they don't need anyone's approval which is why they have called it such. A classic rip-off style if you ask me.
They don't even have a red buttonhole; but then if they did, they would be in trouble.

Mycroft’s popularity doesn’t surprise me at all. He is, after all, incredibly beautiful, clever and well-dressed. And beautiful. Did I mention that?
