Do I have a hand sample PJ?

I purchased this 1972 SunSet Malibu PJ with a bunch of other dolls from a seller on Etsy. Her left foot is torn off.  What happened to her left foot?

But the real mystery is: Is she a Mattel hand sample? I've never seen this style of Malibu before.

The flower decal could have been added later,

but it sure looks like it belongs on the swimsuit!

The flipped-up curls at the end
of PJ's hair are unusual.

When did Malibu PJ get bangs?

 

First of all, this PJ has beautiful side swept bangs.  And although you can't really see it, the hair just past the bangs are feathered.

Her hair is unusually thick. You can see the part in the back for her ponytails. Her hair is curled/flipped up at the end rather than being straight.

PJ's ears are pierced. None of the girl Malibu dolls had pierced ears.  These are not the holes where the sunglasses were sewn in, as those holes are farther back on the head.

Her swimsuit has an attached decal.

I realize that all of these details could have been done by a previous doll owner, except for the thicker hair.  But the previous owner would have had to spend hours revising the hair, making the bangs stay flat and the ends curled up.

The doll was probably given away after her foot tore off, but I doubt the owner would have done so if she'd worked so hard on the hair!
