When were net underskirts worn?

Net underskirts were primarily worn during the 19th century, particularly in the Victorian era, as part of women's fashion. They were used to create volume and shape beneath skirts, often made from materials like tulle or netting. While their popularity peaked in the mid to late 1800s, variations continued to influence fashion into the early 20th century. These underskirts fell out of fashion as skirt styles evolved and became less voluminous.
