And I think the reply here makes my point...
Nothing personal, just a good example.
To be fair, I don't think many gamers would really want their characters wearing real medieval-style clothing, since it was a lot of big dress-like outfits or giant codpieces or curly-toed shoes. Or pantalloons. Or giant ruffs around the neck. Or giant hats. Historically accurate (not that D&D takes place in the real world) but kinda silly and not particularly cool.
1. No.
Tunics were of varying lengths between the hip and knee throughout the medieval era. Higher or shorter due to climate, local fashion etc.. They had dresses too for women. Yes tabards and robes were worn depending on who you were...
2. No. Only the
very end of the medieval era, and only got big some decades after.
3. Only nobles really wore such impractical frippery. Curls and really long points - because Nobles...
4. No, Pantaloon's were an 18th century thing. Medieval peoples used what we would easily recognize as straight up pants/trousers of varying lengths and hose was also common.
5. Nope, 16th century.
6. No, gotta go to the 1820's to see really outrageous hats become a thing amongst the upper classes. Unless you're thinking of stuff like the hennin, which was part of women's fashion later on - because Nobles. But not an normal person everyday thing. And even then we are getting into the late medieval era when we start to see really outrageous fashion come about with the upper classes.
12th century English peasants: Add some weaponry, maybe one of them wearing armor. And they are fit for rough and tumble adventure.
We need to distinguish between what nobles wore as parts of their fashion statements to feasts and important events, and what most actual people wore day to day.
And even with guidelines of what medieval people actually wore, their is of course room for the artists to stylize things to make them a bit more fantasy. i.e. more "adventurer cool"...
Compared to say the cover art of the D&D waterdeep dragon heist AP which is more of a depiction of 17th century fashion...
