You could try to find someone to taylor something like this for you. It will be pricey but you'll have the most control about fit and material.

I reccomend etsy. You have to watch out for drop shippers, but by being concious you can normally find high quality hand made clothing.

Signs it's a real person making what youre buying:

• Custom fit options (can send your measurements)
• Similar materials used in the different designs
• Photos use mannequins or the same model or have the same background
• The designs cannot be purchased elsewhere
• The blurb gives real information about a real person & their story

Also: once you've found a clothing maker you like, you can often buy directly from them, bypassing etsy taking a cut of the profits.

Heres one I found: https://www.etsy.com/listing/1069069106/dark-red-anorakvintage-trench

In general tho, there are some really unique and cool clothing makers on etsy and I've gotten some of my favorite things from creators who sell using that platform.

Good luck finding the jacket of your dreams :)

Pendelton is great stuff. They have a number of shirt/jackets that might work for you. Though none are solid colors

I wonder if dying a denim jacket would do...
