Fashion is constantly evolving, and so are the styles of women’s underwear. At one point, roughly 200 years ago, women’s underwear consisted of three to four layers of clothing under a dress, which somewhat resembles women’s thermal underwear or base layers now. Now, women’s underwear consists of fewer layers, often only one or two. Women’s thermal underwear and base layers are made to keep the body warm without a lot of bulk. Women’s underwear has also gained technology, such as slimming panels and microfiber camisoles that smooth the female silhouette. Women’s underwear from great brands like Calida of Switzerland, Terramar and Moving Comfort offer support and comfort.
