From TheCraftOfClothes Etsy store:
These A-line zero waste culottes come in twenty sizes, to fit a 66cm/26" waist to a 163cm/64".
They are designed to sit on the natural waist and feature a waistband with a button fly. A fly front or back zip can be substituted for the button fly, and the waistband can easily be adapted to have back elastic (instructions included).
There are pockets in the side seams.
One pattern makes two culottes styles: regular classic culottes and culottes which look like a skirt at the back. The culottes can also be adapted for menswear.
The length of the culottes is dictated by the fabric width. Three lengths are suggested - 54cm/21¼, 73cm/28¾" and 103cm/40½" - based on 112cm/44" and 150cm/59" wide fabrics. However, the culottes can be made any length depending on your fabric width and preference.
Suitable fabrics include lawn, cotton, linen, drill, gabardine, wool, and denim in plains, checks or stripes.
