Two  long  gowns, one has  scalloped  edging.  One is clearly handmade, old cotton, perhaps salvaged from an adult  garment.
Tiny hand stitched buttonhole  and tiny  button.  
The scalloped  dress  has some  distressing, see  photos.
Including a victorian lace collar, that would look lovely on this gown. 

From the estate of doll maker and costumer, Mary Lambeth. She collected infant clothing to use for her period reproduction doll  clothing/costumes.
