Pattern adjustments for bandy legs or knock knees - the original is in ? Russian so I am purely speculating here. Adjustments are in the side seam! Initially I thought they were the wrong way round..anyhow, I thought it was very useful!
Even the most wonderful pattern does not include all the features of our figures, and needs to be adjusted. Identified with the fitting trousers defects can be eliminated.
Finally! A diagram that matches 'butt' size with back seam slope.
