An overshirt (also known as a shirt jacket or "shacket") is a garment that combines the features of a shirt with the functionality of a lightweight jacket.

Ideal for transitional seasons: It is the perfect choice for spring and autumn, when the weather is changeable.

Style: It can be worn open over a blouse for a casual look or buttoned up for a more sophisticated look.

Layering: On very cold days it can even be worn under a heavier coat or jacket as an intermediate layer
