1966 paper doll set creates a mystery

 Did Skipper and Skooter go to a private school that required uniforms?  That's the question raised by Whitman #1976 from 1966, Barbie, Skipper, Skooter paper dolls.  There is no "and" or ampersand in the title, just a comma.

As you can see in one of the photos, Skipper and Skooter are wearing matching blazers and pleated skirts, like a school uniform.  I don't remember public school students wearing uniforms in the 1960s, hence the question about private school.

Those are the only outfits from this set that match.  However, all three have pajamas and robes, winter coats, and numerous other dresses.  Skipper has a riding outfit and Barbie has a weird pants set with a harlequin shirt.  None of the clothes are from Mattel outfits.

Note that in the 1966 paper doll set,
Skooter is taller and larger than Skipper.

The inside of the folder shows a department store dressing room.
The only Mattel outfit seen in this set is
Barbie's Country Club with its price tag.

An unusual touch on the back of the folder--
Skipper totes the Skipper and Skooter carrying case.

I think the Barbie in this paper doll
set looks like Tippi Hedren!
