First up is a simple, one piece nightgown. Joyce found the pattern for free here, and reduced it and tested it to fit the Tiny Rag Doll. Joyce's version uses only one layer of fabric, to reduce bulk at this tiny scale. For my nightgown, I used the lines on the pattern as sewing lines, not cutting lines. This pattern can be made into a dress, embroidered, embellished, shortened for a shirt, and on and on.
Finish the neckline with tiny overcast stitches, turn and sew, or make a small facing. I used the facing method, which just meant that I made another pattern piece of the neckline only, and sewed it to the neckline with the right sides together. Clip the curves and turn to the wrong side.
You can also modify Ann's camisole and pantaloons pattern to create rompers or overalls for your doll.
And here are the instructions for these modifications:

If you like, you can modify Ann's dress pattern to also make a shirt. Simply shorten the length of the dress, and eliminate the 'flare' of the dress below the sleeve area. Here the shirt is paired with overalls, for a sweet country look:
