This got me thinking of what specific part of the 1800-1820 time period would be easiest to create with minimal cutting. I decided on a neoclassical/very early 19th century- inspired design. I figured a neoclassical look would be the best to minimize cutting given that the focus was more on drapery than a tailored look. In fact, the ancient garments from which the early 19th century drew inspiration were often made up of more or less complete lengths of fabric woven to size, and, when cut, were made with little to no waste fabric.*
*I think there may be an interesting discussion of this in Dorothy Burnham's Cut my Cote, which explores the history of clothing cut to loom widths in various cultures (and has DIAGRAMS!). I can't remember if there was any mention of Classical Antiquity in it, but a very good book either way.
