Evening is a word commonly used in the footwear industry to indicate women's shoes designed for casual, formal, or special occasions in the evening. Evening footwear styles vary widely in design and color, and one may choose different types depending on the formality or informality of the attire they are meant to complement. Still, the most popular styles generally are pumps, ankle straps, and slingback sandals with medium to high heels in shinny uppers or decorated with sparkling ornaments.
