Barbie's PAK cardigan was available on the market from 1962-1963 and was available in blue, black, white, and pink. The blue version is the same sweater found in Mood for Music. Earlier versions, which are harder to find have knit-in bands and later versions have sewn-in bands. When shopping for vintage Barbie sweaters, inspect them carefully for holes. It will be easier to get this sweater on Barbie if you cover her hands first with gloves or a small piece of Saran Wrap. Near mint examples can be found for about $35.
