yes. I do Jousting & skill at arms on horseback which are both a sort of re-enactment.
Its a lot of fun!
There are many people around the world who are part of SCA groups and other WMA groups who do this sort of thing obn a regular basis.
At our international tournament in Feb we had several legions of Romans plus many other re-enactment groups including a bunch of wild men in animal skins.
We knights pay a reaonable amount of care to getting costume correct [or as correct as we can given cost, time and materials].
The armour that we use is real armour, designed on the same style and methods as the originals. Our costume is as close as we can get to how it looked although some of us cheat and use sewing machines, there are others who will only handsew everything. My maille is made of spring steel however the construction methods used are the same as if it had been made in the 14thC.
My horses are more "correct" than most of the ones seen overseas, they are real destriers of Spanish breeding, nimble, quick and very noble, true mounts of knights and kings, not the hefty carthorse X's so often seen.
My sword is a battle ready broadsword which I can cut things with, my dagger is a functional item also.
