From Truly Victorian:
Circular skirts were very popular in the mid 1904-1907, when very full, straight skirts were the most stylish. Known as a circular skirt in two parts, there is a seam at both center front, and center back. The back is fitted, in habit style, with a 6″ sweep. The closure is in the center back. With the seams cut bias, this skirt is especially suited to stripes and plaids, which form a chevron effect at center front and center back. An optional band of fabric can be added to the skirt to simulate a pointed tunic.
This skirt requires 54″ wide fabric. This skirt can also be cut cross-grain with the center front on a fold, which will require 60″ wide fabric for skirt lengths over 41″ long (front length.)
Waist 20″-46″
