Finished this generic "early period" kirtle (or cotehardie) today. I suppose it would date to around 1100-1300? It's not meant to have an exact date. This is a camping dress for Pennsic, to wear to the showers, right out of bed, when it's too hot for late period, and around the camp.
Linen blend, with machine "goldwork" embroidery on the neckline and cuffs instead of trim. No lacing, just pulls on over the head, but is rather fitted. The belt was quickly thrown together to add a bit more bling to such a simple dress.
I have another aqua linen kirtle nearly finished, but that one has eyelets (like, 30+), so it's creeping along steadily.
