Joe, ya look plumb dandy in yer outfit. And it's a very familiar look to these old eyes.
Matter'a fact, ya look just like a 1,000 other Buckskinners outta Taos, Eagle Pass, The Mimbres, or The Mogollon Mountains of New Mexico / Arizona.
FWIW: From the Franklin Mountains of Paso del Norte, the very foothills of the Rocky Mtns, to the Canadian Rockies, such attire was very common throughout the nation's early years, including most of the Fur Trade era. (Accompanied by a Buffalo Robe, slung over the shoulder or carried on a horse.)
As you well know, Fur Traders of the Southwest often dressed a little bit different than others, especially those coming out of the High Country of the Rockies with their furs and leathers, and all for good reason.
The high Desert / Mountain Country of that area can go from 100* in daylight hours, to a bone chilling 28* over night, especially in early Spring or late Fall.
Of course, ya ain't located all that far from those very same folks, so I have to imagine your "character / persona" would look pretty much the same as those throughout much of the Southwest.
The Murals on the walls of the old Library at UTEP, depicting 17th / 18th century of Paso del Norte showed the majority of Gringos, Mescalero Apache, Mexicans, Ysleta Tiguas, Pueblos, all dressed just as you in your picture......
Many of our Members who are / were from this same area and have 'vooed' quite a bit, will tell you the very same thing. Your persona as a free trapper would fit perfectly in the Southwest!
Uncle Russ...
