Elizabethan Costume Collection Sewing Pattern: Simplicity 8881
Simplicity 8881 in sizes 14-20 From the Elizabethan Costume Collection designed by Martha MCain. 23 pattern pieces make the gown shown (which is two pieces) and the Farthingale and Bum roll. They even specify the order to make the parts in for best fit.
This particular pattern has no envelope, no idea what I did with it, but the instructions & all the back of the envelope info has been copied and is included. The pattern pieces are still factory folded.
This is an older pattern from 1999 and, in my opinion, you need some sewing experience to put it together; not that there are so many pieces, but you'll be working with a lot of fabric.
