Someone in a great say, colonial kit, but wearing modern glasses or sunglasses... I just try to ignore it.
I got a kick out of the photo of Dick "Beau Jacques" House on page 1 of the first Book of Buckskinning, decked out in leathers with a straw hat on his head, modern eye glasses on his nose, and a digital watch on his wrist. He wrote about "The philosophy of Buckskinning." It was looser back in 1981 on what you wore at rendezvous, I guess.

Yes,.... there has been a bit of division between the two sports known as "modern buckskinning", and those that desire to "re-live history" as accurately as possible.
Some folks use sources (such as movies/Hollywood), to determine "what and how" they should look and what tools and guns they should use and carry, when depicting 17th. 18th. and early 19th. century frontiersmen, and mountaineers.
NOTE: Hollywood doesn't much care about being "historically correct", as long as their movies bring in
MONEY,.... we should all be aware of that fact, and accept it for what it is.
On the other hand,.... there are folks that dedicate a great portion of their lives to "historical research", and new (historical) information is being discovered all the time. Some of these folks also put what they have learned into "practical application and survival", by limiting themselves to using only things that can be "documented", and find great enjoyment in going that route.
That's not to say, you'll find them in the woods using only hand forged tools, hand forged wrought-iron gun barrels, and hand forged hardware on their guns, because these days such things are often not practical due to modern limitations.
These fellas (and gals) do however, go to great lengths to accurately re-live history, by brain tanning hides, making their own lodges, saddles, clothing, and accouterments. So they do have a vested interest in doing things the way our forefathers did.
Even the most "hardcore" (dedicated) modern mountaineer will often readily admit that he (and his "trappings"), can usually stand some improvements, and therein lies a big portion of the "never-ending fun" of historical research and the effort to re-live history.
I have met a few "stitch counters" over the years, who have done just enough research to make themselves irritable,.... but they're usually "far and few between".
As for "personas",.... once historical clothing, type and style of weapons, trapping and camping gear (of a particular time-frame), has been made/attained, it's not difficult to establish a believable persona "that fits you well".
I'm a "free trapper",.... I go where I want, whenever I want.
