Young Blonde Girl Wearing The Red Scarf

Uses and types
In cold climates, a thick knitted scarf, often of wool, is tied around the neck to keep warm. This is usually accompanied by a warm hat and heavy coat.
In drier, dustier warm climates, or in environments where there are many airborne contaminants, a thin headscarf, kerchief, or bandanna is often worn over the head to keep the hair clean. Over time, this custom has evolved into a fashionable item in many cultures, particularly among women. The cravat, an ancestor of the necktie and bow tie, evolved from scarves of this sort in Croatia.
