Furbelow

"Her father, it appears, had a grand palace there, with such gardens, bowling-alleys, grottoes and casinos as never were; gondolas bobbing at the water-gates, a stable full of gilt coaches, a theatre full of players, and kitchens and offices full of cooks and lackeys to serve up chocolate all day long to the fine ladies in masks and furbelows, with their pet dogs and their blackamoors and their abates."[1]

Furbelows are the pleated border of skirts or petticoats and can be used as trimming on garments.[2]
