Vintage Mattel 1966 Twist N Turn Turnouts Outfit Twiggy Japan Bendable Rooted

I am not an expert on vintage Barbie’s but this appears to be a 1966 twist n turn Barbie doll with a twiggy outfit - she has bendable legs, twistable waist, rooted lashes - and a Twiggy Turnouts outfit.

In overall good and clean shape - one of her legs is a bit loose where it connects to the hip, there are some blue smudge stains on the back of her arm & some of her fingers look like maybe they got chewed on a bit? - other than that some general signs of age/wear - I’m not sure if her hair has been cut or not.

As far as her outfit goes it’s in okay shape - the string that goes over the button closure is no longer functional.

Refer to the pictures - don’t hesitate to contact me with anything!

Thank you.
