So what I did when removing the lining from the jacket, I kinda replicated what they did with the jacket in the show by removing all of the lining in the jacket, except the lining in the front where it contains the pockets. The jacket is much looser, and baggy.
The biggest problem with the WSL jacket is that whenever I raised my arms above shoulder length, the whole jacket would move up. But without the lining, while it still moves up a little bit, the jacket is more flexible and maneuverable now that the lining has been removed.
Especially if you want to wear it, how Rick does where it’s halfway zip down, the jacket barely moves whenever you lift your hands up above your head. So, depending on your size you order, it will obviously move up from your waist.
