A sweater dress is a type of clothing that combines the features of both a sweater and a dress. It is typically made from knit fabric, similar to a sweater, but has the shape and silhouette of a dress. The sleeves may be long or short, and it can come in various styles such as turtleneck, scoop neck, V-neck, etc., depending on personal preference. Sweater dresses are often worn during transitional seasons like fall and spring when the temperature is cooler but not quite cold enough for a heavy coat or jacket. They provide warmth while also being comfortable and stylish.
