Vintage Skipper Dreamtime #1909 (1964 - 1966)

Pink Swiss Dotted 2 Piece Pajamas with Lace Trim
Pink Robe with Ribbon Tie and Kitty on Pocket
Hot Pink Slippers with Fringe Trim
Stuffed Blue Cat
Blue Phone
Phone Book
Alarm Clock

Though not an exact match, this coordinates with Barbie's Nighty Negligee Set #965 (1959-1964).  (They both have the blue cat!)

This ensemble is easy to find.  Out of all the accessories, the slippers are usually the hardest to find.

On the robe, the ribbon ties can sometimes be problematic - they may be broken off, frayed or really wrinkled and dirty.
