Lingerie businesses sell underwear and related garments for adults, with ranges that may include bras, briefs, knickers, slips, camisoles, bodysuits, corsets, shapewear and nightwear. Products are commonly available in different styles, fabrics, colours and sizes, including options designed for everyday wear, special occasions, maternity, nursing or particular levels of support. Some retailers also stock swimwear, hosiery and accessories such as suspenders or bra extenders. Customers may be able to shop in person, online or through both channels. In-store services can include measuring and bra fitting, advice on fit and garment care, and help choosing suitable styles. Retailers typically offer standard sizing alongside specialist ranges, although the sizes and services available vary. Some businesses focus on particular products, such as bridal lingerie, larger cup sizes, post-surgery garments or lingerie made from specific materials.
