Chanel’s 1955 handbag with a rectangular Mademoiselle lock and chain strap is the Chanel 2.55.
Gabrielle Chanel created the bag in February 1955, which explains its numerical name. Its design drew on details associated with her life, including a burgundy lining linked to the uniforms at the convent where she was educated. The chain strap is often connected with the key chains carried by caretakers at the convent.
The 2.55 is frequently confused with Chanel’s Classic Flap bag. The Classic Flap is a later interpretation that uses the interlocking CC clasp introduced under Karl Lagerfeld, while the original 2.55 is identified by its rectangular Mademoiselle turn-lock. Both designs are quilted Chanel handbags, but they are not the same model.
The bag’s quilted construction, chain strap and compact rectangular profile have made it one of the most recognizable luxury handbags. Variations have appeared in different materials and sizes, but the February 1955 origin remains central to its identity.
