Businesses selling children's clothing provide garments for babies, toddlers and older children, with ranges that may cover everyday wear, sleepwear, underwear, outerwear and occasion outfits. Products commonly include tops, trousers, dresses, skirts, knitwear, coats, jackets and waterproof clothing, as well as socks, tights, hats and other accessories. Some retailers also stock footwear, nursery clothing or school uniform, though the selection varies. Clothing is generally offered in age-based or measurement-based sizes, with options for different seasons, activities and stages of growth. Customers may find items made from materials such as cotton, wool, denim and synthetic fabrics, including clothing designed for warmth, comfort or ease of movement. Shops may offer help with sizing and fit, and some provide alterations, personalisation or gift items. Sales may take place in physical shops, online or through both channels.
