I looked through the photos on IMDB and IMFDB for inspiration.
The first thing I noticed was that the hoodie was absent quite a bit when he was wearing the jacket.
Then that Mondo failed to add the cartridge loops to his belt:
Thinking on the possibility of going the rolled down flight suit look, it would suit my modified body with the traps cut down...
...but the suit is so tight and hard to get over his shoulders, even with them having been reduced, that I don't want to risk removing it again in case it rips.
When I was testing the body I liked the option of having the jacket undone as it showed more of the flight suit and belt, and since I can't decide between flamethrower and shotgun I've been trying both in a preparation for battle scenario.
While the arms are much more workable now, the legs are still a problem and will only accept a wide stance.
If the flamethrower nozzle is going to be facing forward, the recess needs painting black.
The jacket needs buttons on the pockets and fur on the collar. Buttons are easy enough though I don't know which way to go for fur. I have some sheets of sticky back felt that's the right colour and should look in scale.
I tested my theory that Mondo's jacket was no good to man nor beast, but maybe more suited to a small female figure, so tried it on Young Rich's skinny Zendaya 'MJ'.
From side to side the fit is pretty good:
It looks bulkier viewed from side on, but it's comparable to the volume of an RAF Irvin flying jacket:
It doesn't help that the collar refuses to lay down, which would take up some of the material.
As a jacket I've seen worse tailored examples. It was just several sizes too small for MacReady, or any male figure wearing layers of clothing, which made it look utterly ridiculous.
I tried it on him after reducing his traps, biceps and sides, and it was still just as unworkable. Not enough material to allow it to sit on his shoulders, which became even more apparent when moving the arms which stretches the material to the max.
