From Truly Victorian:
This skirt is of the style used during the transitional period of 1868 to 1872, when the hoop was giving way to the bustle. It is designed to be worn over TV108 Grand Bustle, or a small elliptical hoop. The very full skirt is fitted to the waist in front, with the extra fullness shifted to the back. It has the traditional five gores and a full width in back. The placket is in the left side back seam. A pocket is in the right side seam. The hem is floor length in front, gets longer at the sides and is demi-trained with an 8" sweep in back.
This skirt is suitable for just about any use. This skirt can be left plain, as many post civil war skirt were, or heavily decorated as in the 1870's. Mix and match overskirts for different looks. This pattern also can be used for petticoats.
