Help with documentation for linen clothing

[frualeydis]

Having read and re-read Riitta Pylkkänen's article on the 15th century fragments of linen garments from Rauma in Finland (of northern german origin) I've conclusion that they may as well be smocks, as kirtles, as I previously thought. A very shaped smock, but still. of course they could still be kirtles, but in any case it leaves me without certain documentation for linen kirtles worn as middle (or outer, but that's not what I'm looking for) layer in either late 15th or early 16th century Germany, which is annoying since I had a cunning plan involving hand woven linen.
I know that linen outer garments are mentioned in the Tacitum Sanitatis, but that's a bit early and bit far south for my preferences.
I'm, of course, specifically looking in the direction of mmcnealy, but any references to either texts or preserved garments are very welcome.
