Hi...you can easily adapt a regular pattern for a simple vest I'm sure, and just add the petals. The skirt is just a gathered skirt that doesn't require a pattern, but you should also be able to find a regular commercial pattern for a simple skirt in her size. Your daughter is too young to compete, so it doesn't have to be to regulations. Unfortunately, the patterns that are available for these costumes don't come as small as your daughter's size.
