Young Blonde Girl Wearing Long Sleeved Sweater On The Deckchair

Customary wear
Thin sweaters may be worn tucked in to the waistband of trousers; but otherwise, men's sweaters are to be worn untucked. Nonetheless, some individuals, including some television and film actors, have been known for wearing tucked-in sweaters.
Sweaters are a versatile item of clothing and can be worn on top of almost any outfit. Sports sweaters, especially hoodies, are often worn on tops of sports kit while traveling to or from a sports ground. Sweaters can be worn with a dress shirt underneath (and optionally a tie), which has the advantage of allowing the wearer to have the option of removing the sweater when it is uncomfortably warm and still looking presentable in many situations. In the late 20th century the sweater increasingly came to be worn as an alternative to a shirt when finer materials made them more comfortable next to the skin.
Some women's sweaters are meant to be worn belted; a belt or drawstring is sometimes knitted into the sweater itself. Leggings are commonly worn with long sweaters or sweater dresses.
