The "Aerienne" registered brassiere was a type of women's undergarment that was manufactured and sold by the Lily of France Corset Co., Inc. The company was located at 625 Broadway in New York City.
The brassiere was advertised as being "boned throughout with walohn," which was a type of flexible boning made from a synthetic material. This was designed to provide support and shape to the garment, while still allowing for a comfortable fit. The brassiere was also advertised as having a front-lacing design, which made it easier to put on and take off than traditional back-lacing brassieres.
The Lily of France Corset Co., Inc. was a prominent manufacturer of women's undergarments during the early to mid-20th century. The company was known for its innovative designs and use of new materials and technologies, and was a major player in the competitive lingerie market of the time. While the company no longer exists today, its legacy can be seen in the continued popularity of many of its classic designs and styles.
