From back of envelope: Misses' and Women's Nightgown and Panties. Yoked nightgown with front neck vent and sleeves gathered by elastic in casing. A and B have eyelet trim. C has buttons and thread loops with collar, pocket and lace trim. Panties have elastic at waist and leg casing.
(See! It says "panties" right there on the envelope! It's not my fault, I HAD to write it!)
Pattern is cut but complete; instructions are complete. Envelope is slightly wrinkled with one small tear at the flap, and there is some yellowing. Copyright date is 1971.
