In countries where the weather is cold, underwear is one more layer of clothing that helps the wearer to keep warm. Underwear can be used to keep the wearer modest – for instance, some women wear camisoles and slips (petticoats) under clothes that are see-through. A camisole is an item of clothing without sleeves that covers the top part of a woman's body, while a slip or petticoat is a kind of skirt that is worn underneath an outer skirt. On the other hand, underwear can also be worn to make a person look more sexy. It is possible to buy underwear made specially to excite another person in a sexual way, such as underwear that can be eaten (it is usually made of small sweets stuck together) and underwear with holes cut into them.
