edit, looks like it's supposed to be that way...and I never even bothered to check the fabric content, it's wool, alpaca and cashmere. I was worried for a minute because I've never seen anything purple label, except for ties, at the outlet so I figured maybe some seamstress went on a gin binge and screwed this thing up and it consequently ended up at the outlet
Well, upon studying the jacket closer I noticed that one of the top pockets is at an angle, and the other isn't. It's actually at a pretty extreme angle compared to the other pocket, which leads me to believe that there's no way someone could have accidentally sewn it on that crooked, but rather it's an intentional design characteristic. I don't know - what do you guys think? Another way to tell would be to find another picture of this jacket, but I haven't had any luck in doing so. Warning: Spoiler! (Click to show)
My guess is that the pocket is canted a bit for ease of use. It's much easier to slide your hand into a breast pocket that is slightly turned. Try it yourself; put the jacket on and see how much easier the canted pocket is to use over the other pocket.
Perhaps the jacket didn't come that way, and the gent who owned it had it custom tailored to fit his needs. Maybe that's the pocket he put his shotgun shells in, or his compass, or something like that. Something that he needed to be able to easily access. Anyway, that's my speculation.
This is my first post here, and I reckon I'll be posting quite a bit more. I find this thread fascinating.
