Evening wear refers to formal clothing worn during special events or occasions that take place in the evening. This type of attire is typically elegant, sophisticated and dressy, with designs that are meant to impress and make a statement. Evening gowns for women and tuxedos for men are common examples of evening wear, but there are also many other options such as cocktail dresses or suits that can fit into this category. The key is that the clothing is appropriate for an event held during nighttime hours and is meant to be worn when socializing in a more formal setting.
