Brunette Girl Strips Her White Undergarments On The Green Antique Couch

In cold climates, underwear may be an additional layer of clothing that helps the wearer keep warm. Underwear can be used to preserve the wearer's modesty – for instance, some women wear camisoles and slips (petticoats) under clothes that are sheer. Conversely, underwear can also be worn for erotic effect. It is possible to purchase underwear made specifically for sexual titillation, such as edible underwear and crotchless panties.
Some items of clothing are designed as underwear, while others such as T-shirts and certain types of shorts are suitable both as underwear and as outer clothing. The suitability of underwear as outer clothing is, apart from the indoor or outdoor climate, largely dependent on societal norms, fashion and the requirements of the law. If made of suitable material, some underwear can serve as nightwear or swimsuits.
