Didn't get time to make a fancy dress, but at least she's clothed! Made the on land outfit versitile by leaving the "shirt" long and unfolding the sleeves for a nightgown and then add skirt, fold up sleeves and she's ready for the day. Then the mermaid tail/shirt are attached together for ease of use.
Have to wait until tomorrow afternoon for her response, but I think she'll figure out who it is
