I am just doing a box pleated kilt - as I made a plaid to take on holiday and ended up with one box pleated kilt's worth of fabric left over.

although the OP has not provided any further information I think that I need to sort out my own thoughts on this problem.

First, the lower edge of the fell seems to need to be sewn down in order to check that it is in the right place and it fits, so I tacked along the visible fold lines from the lower edge upwards to the edge of the fell, then folded the pleats and tacked them together at what I think is the right level.

In order to taper the pleats I think that I will have to cut the inner folds, or have a central triangle of five layers in an otherwise three layer thick fell.

Although I know the difference in measurement at the waist and hip, I am not sure that the best fit will be got by sewing in a straight taper - I am planning to do the waist line, then use a mirror to see where there are gaps between the edges so as to widen the pleats at those points.

Once I have done one it will be possible to make templates from it to see what the shape needs to be and - hopefully a second one will involve less trial and error.
