Vintage Barbie's sister Skipper from the 60s

Barbie's sister Skipper was produced by Mattel around the mid-1960s, possibly 1966-1967. Sent from abroad. Searching online did not reveal the exact production year of this model. From the clothing and accessory set, only the white blouse and red skirt with suspenders have been preserved. The rest of the clothes were sewn in the 1980s from various fabric scraps. There is a minor defect - the leg attachment has been repaired.
