Simplicity 8466 pattern is a wardrobe suitable for 11 1/2 - to 12 inch teen dolls, from 1969. Pattern has been used very carefully and I have gone through the pattern and all pieces are present and in very good condition.
Simplicity 4883 is also a pattern for teen dolls. It is not dated but pre zip code era. Pieces are used and pattern is still in good condition. 2 small pieces are not present, it is the suspenders for the jumper and the bottom ruffle for the slim dress. You might be able to use the one long piece that is there and considered a waist tie for a pattern for the others.
Some wear to the envelopes but securely holding the contents.
