From the 1920s era here's a white cotton baby dress that would work well for a suitably sized doll. The dress has tucking, drawn thread work and embroidered detailing as well as lace trim at the bottom. There is no label, but it was most likely made in France.
Sizing: No size is indicated, but please rely on the following measurements for fit:
Shoulders: 16 1/4” across the top, including the sleeves
Chest: 21” around, taken under the arm openings
Overall length: 21 1/2“, including the bottom lace trim
Condition: It does have a couple of small condition problems. There is a tear at the bottom of the back opening (see last close-up photo), usually hidden and really very minor. There is also a very light mark at the upper front and a teeny tiny one at the back near the tear - both of these are extremely minor and amplified in the close-up photos. The is easily repairable for someone with some sewing skills. Otherwise, very clean and looks to have seen very little use.
This is a very pretty vintage baby dress that would be great for the right doll.
