with the complexity of the monster maroon, perhaps the economies of doing a survival jacket might be and easier hurdle for the group!
The TWOK uniform jacket is a walk in the park compared to the Field Jacket. Uniform jacket stems from classic menswear in cut and material - something Magnoli is specialized in. The "two-ply" flap and sleeve trapunto are the technically challenging parts. We could even start this off with the Roddenberry patterns - I and many more here have them, I'm sure. There are some details in the patterns that need accurizing, but once that is done, they would serve as an ideal starting point.
As for the wool debate, I seem to remember that it's supposed to be that. Not gabardene, but 100% wool, a quite fancy fabric IIRC. And yes, they used white and dyed it. Cost-prohibitive, if you ask me. [beaten by Got Maul!]
As for the Field Jacket... it's a different beast. Complex pattern - yes. Lot of metal and plastic detailing that is hard to find... peter1701, what happened with the Field Jacket project over on ASAP? I believe someone actually sourced some of the metal clasps and whatnot over there.
There's the orange zipper with te weird ball-shaped pull, the huge off-white collar, phaser pocket, specimen sample pockets with plastic lining/inlays... oh, and there's the Miarecki box/emergency beacon/cigarette case thing as well... lot of junk in that jacket!
I'd basically kill for one, but a truly SA one would cost stupid amounts of cash.
Here it is though - I got this pic from a guy who, for years ago, was fortunate enough to try on the Kirk jacket (you can find a report on the IDIC pages):
It's a beauty.
I'd rather start with the basic uniform. It's doable with a
relatively small effort compared to the above behemoth of a jacket.
Sourcing SA insignia might be a bit tricky. Here's what an accurate Starfleet badge should look like - the originals were two-parters while the available replicas are cast in one piece.
A person who is banned here arranged a run from the original maker of the screen-used insignia a few years back, but like many other projects this guy started, it went south... payments were sent, but as I recall it, not everyone got their stuff...
