Spirella
Spirella was a company which manufactured made-to-measure corsets. It was founded in 1904 and was bought in 1989 by the rival Spencer company. It had factories in the USA (New Haven, Connecticut, Meadville, Pennsylvania) and the UK (Letchworth, England). Its most popular corset was the Model 305. Spirella products were not sold in shops. Instead, staff called corsetieres were sent to its customers' houses.
