Coco Chanel introduced the 2.55 handbag in February 1955. Its name refers to the month and year of its launch: 2 for February and 55 for 1955.
The bag became notable for combining a quilted body with a chain strap, allowing the wearer to carry it over the shoulder or across the body. Before this design, many women’s handbags were carried by hand. The shoulder strap reflected Chanel’s interest in practical freedom of movement.
The original 2.55 is associated with details such as burgundy lining, a rectangular “Mademoiselle” turn-lock, and a hidden zippered compartment. Later Chanel bags used the interlocking CC turn-lock, which is distinct from the original 2.55 design.
The 2.55 is often confused with every Chanel flap bag, but the terms are not identical. “2.55” specifically identifies the original February 1955 model, while “Classic Flap” commonly refers to later versions that use the CC clasp.
