My darling Millie (by Kaye Wiggs) has been testing the clothing I make for Little Fee Jessica as they are similar in size, though Millie is 3cm taller. Here are two examples that would work although I think the green one is too short. The pink one is a much better length for a young lady!
Here is Jessica in the original version of this dress so you can see the length on a Little Fee:
Have a great day!!
