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.
You'll find this layout on various outdoors outerwear jackets and even some Belstaff-type motorcycle jackets.
Now about this new experiment for treating stains...
What I've done is take them to the cleaners, explain that I sell used clothing (i.e. these aren't mine) then open the pants and say "Can you give it an extra dose of something special down here?"
They come back clean. I've done this three times already.
