Recently got this USN Denim Jacket from Real McCoys. 10 oz denim.

It was no-wash, and shrank a lot. You can see a lot of shrinkage in the chain-stitching across the top of the pocket in the below pic.
Even after the wash the sleeves were very long… so I decided to do a home-style stitching.
A blanket stitch using my leather stitching tools and linen thread.
The coat buttons are listed as iron. They are a flat black, but I’m expecting that they will burnish over time to something more like the Buzz Rickson’s version of this jacket.
