Identifying Authentic 1970s Polyester Cape

Authentic 1970s polyester cape pieces (1970–1979) are among the most sought-after items in antique fashion. Synthetic polymer fiber commercially introduced in the 1950s, ubiquitous by the 1970s. Excellent durability and wrinkle resistance; the defining fabric of 1970s fashion.

When examining a potential 1970s polyester piece, the most important diagnostic features are construction method, closure type, and fabric authenticity.Sleeveless outer garment hanging from the shoulders. Used as an outer layer across multiple eras from Victorian cloaks to 1960s mod capes to 1970s boho ponchos.
