Bias Shaping? Answering Sarah's Request

On a post a week ago, “Creative Technical Design Solutions, 1960 Bias Shape”, Sarah asked in a comment, “How do you stretch the bias? Are the skirt panels cut mirror image for symmetry?” I repeated the photo for everyone to see again. Note that the skirt of the dress I cut on the bias, and it is attached at the empire line. It is cut in four panels, a “pair” in the front, and a “pair” in the back, because the front and back, of necessity, are slightly different shaping. “Mirror image for symmetry” is a correct understanding, but we use the word “pair” in the industry. Also note that it “skims” the waist rather than revealing it, and it is an “A-Line” shape from hip bone to hem. That is, the flare of the hem is a straight line from hip bone to hem. All 3-D curvature is caused from the bias and the flare at the hem is caused by stretching the bias at the empire line.

I made three sketches to describe the process. These two words are emphasized because I want all to know this is not telling you how to make the pattern. They are rough sketches to help you see the process in your mind. The first is simply a 2D sketch of how the eyes sees 3D. So many beginners do not understand this, and call it 3D. The second sketch, please note has the same hem sweep, but is much narrower at the empire waist, and is stretched to the proper measure for matching the top. The third sketch is the lining, that has a dart to shape it. It is sewn totally free from the skirt shell. You need to develop the lining shape first, which then, on the dress form, is a base for stretching the bias of the shell in silk doupioni properly, by draping the pattern shape. Every different fabric has a different falling bias, and needs to be draped. This kind of shaping can never be accomplished flat on the table.

Interestingly, in one of Tess’s new shaped coats, I had her stretch the cross grain of wool at a high rise waist to accomplish something similar but much less sweep.

Let me know what you think, and if you can understand this in words. I’ve always done it by demo’s.

Creative Technical Design Solutions, 1960 Bias Shaping

Many have been asking for more stories on my past creative technical solutions. When you are intensely creative then you also desire to create different ways to solve technical problems, while making the style even more beautiful in shape for the ultimate consumer. In my early collections in the late 1950s and early 1960s I did a lot of bias cuts, which I love. As I played with the bias I realzed that you could do some masterful tailoring by manipulating the bias in various ways.

Here, in this silk doupioni dress, the skirt section was bias cut, and I "stretched" the bias at the empire line seam, and the fall over the body and indenting at the waist was superbly feminine, with it's gentle waving at the hem. The top was a series of tiny box pleats, with the pleated frill a separately sewn piece. It was easy in the 50s and 60s for a young designer to get small lots of this pleating done. The model is Jo Summers, who today, owns the Copley Seven Model Agency, and owns some of my past styles. In fact, I sold this model quite well, directly to consumers from fashion shows.
