From Truly Victorian:
This petticoat bustle is based on an actual garment as seen in Harper's Bazaar magazine. This pattern will create a moderate sized bustle, proportioned to your hip size (one size does not fit all). It can be used as support for either 1870's or 1880's style of bustle dress. When combined with the TV170 Victorian Petticoat, you have the perfect foundation for you bustle dresses. This petticoat has a center front closure, and four hoop bones built into the back. This design allows for structural support for heavy skirts combined with ease of movement and wearability (you can sit down without making any adjustments to the bustle!!)
No other bustle pattern can offer this amount of comfort and style. Just put it on and forget it. Petticoat will also fold flat for ease of storage.
