Through the middle of the 1870’s, the bustle continued to

grow larger and had more pads that had strings and ruffles.

(1870 crinolette was the first step out of the crinoline and into the bustle.  By the mid-1870’s, there were many elaborate and decorative pads and structures considered to be early bustles like this “horsehair pad”.  They were named for their stuffings.)
