Beanies are a type of headwear that have become increasingly popular in recent years. While the term "beanie" is the most commonly used word to describe this style of hat, there are a variety of synonyms that can be used to refer to it. For example, some people might refer to beanies as knit caps, wool hats, or even skull caps. Other synonyms for beanies might depend on the material they are made of, such as fleece, acrylic, or cashmere caps. Regardless of the word used to describe them, beanies are a versatile and stylish accessory that can keep you warm and on-trend during the colder months.
