Keep in mind that a lot of the "country" folk would have worn what was acceptable to their lifestyle-which didn't always mean a kilt. Might be dissapointing, but an overgrown linen shirt or leine probably was more than common in this era-combined with a overgarmet for warmth...On the warrior side, this was the era of chain and modular plate, so...unless you were well to do, you probably would have been wearing your regular cloths to battle with a padded gambeson.
