Raye: You have to understand a little something about medieval fashion to understand what's going on here. They didn't actually invent pants as we know them today till quite late. Until then, they wore those baggy shorts called Braies and would actually tie leggings called Chauses, one for each leg (which it became fashionable to mix and match so you often saw people with one blue legging and one red) on to them. They've simply neglected to tie their chauses on to their braies because they're simple folk. You can see the chauses properly tied on with some of the character models in the game, mostly noblemen. Though usually they would wear a tunic that was long enough to cover the bries.
Also, I have seen people refer to Roche's errr.. hat, as a 'turban' it's not. it's a hood, which he has rolled up to wear as a hat. You take the face opening, roll it down and the neck/shoulder area and the pointy bit at the back (which could sometimes be very long and used to wrap around the neck) hangs down the back and sides. It was very, very rare to have a hood that was actually attached to a cloak or any other piece of clothing, hoods were usually completely separate and when not needed as an actual hood would either be draped over the shoulder or worn rolled up as Roche is doing.
This is a very informative post! Thanks for all the details on the clothing.
