The term 'hat style' can refer to two different types of hats: a BOATER (6 letters) and a snapbrim (8 letters). A BOATER is a stiff, flat-topped straw hat with a brim that is usually wider at the front than the back. It is often associated with summertime activities such as sailing or rowing. A snapbrim is a type of hat with a brim that can be snapped up or down. It is typically made of felt and is often seen in formal settings. Both styles of hats are popular choices for special occasions and can add a touch of sophistication to any outfit.
