I don’t think well in three dimensions. I have a lot of trouble translating shapes to patterns, or interpreting patterns to understand how they fit on a body. That’s partly why I love the unstructured early period clothes based on making best use of fabric through rectangles and triangles. I can cope with draping as a pattern technique, but that’s about my limit.
Yesterday, I was thrilled to discover two websites that make sense of how to fit the bodice of a cotehardie and, even more importantly, explained the arms and armscyes. They can be found at http://www.cottesimple.com/ and http://www.mathildegirlgenius.com/FittingAndConstruction.htm.
Both dressmakers waste a lot of fabric, which I think is inconsistent with historical practice. Also, I need to do a bit more digging to understand the relationship between the dresses they are designing and the gores I have seen on many examples, which reach right up to the armscye. The difference may be explained by the fact that I prefer the earlier cotehardies, and these dressmakers are looking at styles well into the 15th C. I think I will use my old rectangle and triangle technique, with the full gores, and then do the fitting on the gores – that matches the artefacts I have seen.
