Guidelines to always follow when drawing pantsu.

1. The area of the elastic band over the waist and hips. Depending on the material of the pantsu and the length of the strap, the creases here vary.

2. Unless it's extremely tight, you can put creases in this part. I usually put a lot.

3. The area where the rear cloth material joins the crotch. I feel that having these lines helps to make it feel more "pantsu" like.

The appearance of the fabric in the back varies with the type of pantsu. "Full-back", etc...

Creases like these are drawn by making shapes like "ハ", "Z", or "6".

TL: He is referring to the shape of the characters above, apparently.
