This tuorial is on making an "A"-Line Kurti. It is very easy and the draft pattern is quite similar to that of a straight-cut kameez/kurti except for that it widens as we move down and has a flare.
You can find the drafting in this tutorial. You should note that here, the width AB is (hip + 3"). Hip measurement would be as mentioned in the above tutorial (RS). Take extra 1" along the whole length as seam allowance.
If you would like to give the bottom a curve shape as I've done, then you should mark C as the midpoint of AB and also BD = 3". Join the points making a curve. YOu can therwise simply go with the straight pattern as it is also equally popular.
The edges of the sides can either be closed or left often as a slit. Further steps are similar to the one in the kameez sewing tutorial.
