My under-tunic has decided to be Irish

I think my linen under-tunic has decided to masquerade as an Irish léine.At least an interpretation of a léine.

I've found pictures of this type of sleeve that people have been making a léine with:

Since my sleeves are much too long for my arms, I think the pleats will work great. 

I do feel a bit badly about making a garment without clear documentation. I'd hate to perpetuate a long line of unfounded conjectures. 

I think I'm going to go through with this, and my next wool purchase will be for a Shinrone Gown. The Shinrone gown is an extant wool gown found in an Irish bog near Shinrone, Co. Tipperary, in the 19th century. It has been dated to the latter part of the 16th century. It is currently held in Dublin at the National Museum of Ireland. 

 

So, my dear readers, have you any evidence that validates the pleating of léine sleeves? Would it be too much of an evil to wear this conjectured garment? 

The linen is cut!

I cut into the linen last night. (eek!) I'm keeping my fingers crossed that the lessons I have learned from my muslins were all I needed to know.
I finally settled on making it a knee-length garment, in a men's style. It will have a rounded triangle neck, like that of the Skjoldehamn Tunic. I have made the triangle almost as wide as it is deep, so if I need to change the opening style to a keyhole, square, or rounded it is easy to accomplish at a later date. The sleeves will be uniform width along their length. I have left the sleeves too long for myself. Right now I am still debating whether to just turn back and tack down the excess length, or to leave them their full length and install a drawstring at the end. I decided to leave the length there at any rate, mostly so that this could be an actual men's garment someday. The triangles from along the sides of the fabric will form 4 gore pieces, while the triangles at the bottom of the fabric will form 4 more. The rectangle between the bottom of the dress and the gore triangles will be the sleeves.
