Vintage early 1960s Catalina one-piece swimsuit bathing suit original Barbie

Button straps, belted waist, built-in bra. Vintage size 12, fits like a modern 4. Model’s measurements are 34-27-37. Flat unstretched measurements are in photos. One loose thread on the back (pictured) and the elastic in the legs might have lost some of its stretch. Otherwise good condition.
