Sounds good. That's most likely what I need to get.

I should clarify something I stated before in case anyone starts reading this thread at this point. I wasn't talking about wearing a leine or a period correct garment under the plaid. I was thinking of the way the scots used the shirt or tunic as a garment that could be worn alone or with the kilt. I'm thinking of a modern practical garment like a long t-shirt or nightshirt because that is how the plaid will be being used.
