Fall Overcoat - is there a technical name for this type of collar (aside from crazy, ugly etc.)
Interesting. Not in a particularly good way, but still, interesting. It's difficult to tell whether the collar is popped or not. I actually suspect not, given the low height of the collar at the back and still quite large gap in the middle of the chest, and instead it's actually designed to always look that way. I would be surprised if this style has a specific name; it's certainly unusual. If you were thinking of getting a similar coat made for you, I suggest just taking the photo to your tailor. Then wait for the stunned bemusement to pass, before asking whether they want to try replicating the design. ;)
They have already expressed outrage at the thought.
