I was thinking about Viking apron dress design today, and I realized that there is one design possibility I have not explored.
I have made fitted dresses with gores in the lower portion to give them wider skirts, and I've made dresses from flat sheets that wrap around the body, and are secured by placing the brooch pins through multiple sets of loops.
What I have not done is to make an apron dress with a flared skirt that is not sewn into a closed tube--a flared skirt apron dress with the final seam open, so that you can just put it on by wrapping it around yourself and inserting the brooch pins, instead of having to wriggle into it.
I only know of one costumer/reenactor who has attempted to make such a dress. Her version can be seen here. (If you are prompted for a login, just hit the button that reads "login in as a guest" and you will be forwarded on to the picture.)
I think she had the right idea but that the proportions of her design need a little bit of tweaking. So I'm going to add a gored-wrap apron dress to my project list--to be undertaken after the Byzantine outfit is done.
