Her top petticoat is made for a fine stripped cotton lawn that's been trimmed with an embroidered ribbon. Underneath she has one of plain white cotton over her crinoline. Her corset has pulled her baggy shift into pretty gathers, and she's very happy to get her tiny waist back again.
Next she'll be getting a white silk cotton chemisette and false sleeves under a peach gown. Which will have a little ribbon and lace trim.
