I am aware that the medieval period is long and there may have been differences amongst countries. I don't know how much I must specify my question. So, if necessary to choose a time and place, please focus on England, 1300-1400AD.
I read on Wikipedia for this period:
The basic garments for women consisted of the smock, hose, kirtle, gown, surcoat, girdle, cape, hood, and bonnet.
Still, I wonder, how much of the attire women were able to fashion by themselves, given the cloth.
When I was little we lived in the Greek mountains and most women had sewing skills, but I think for something like the kirtle above they generally went to the seamstress.
It turns out the kirtle image is from 1626, so even that is not medieval, but Renaissance clothing (many thanks to the commentator Mr Denis de Bernardy). I will try to find a more accurate one. Until then, I think, it may serve as an estimate for the level of sophistication.
