The Spencer itself is an interesting combination of both a fitted back and drawstring front. Drawstring bodices were typical of the transitional clothing of 1790s. It maintains the center back seam and separate shoulder straps of the 18th c construction but the flairs at the back seams flirt with future construction styles.
The original garment was featured in DAR Museum’s exhibit “An Agreeable Tyrant”: Fashion After the Revolution.
Check the measurement charts for sizing. Patterns are printed on 20lb weight paper, with multiple sizes each uniquely color-coded on the pattern. Includes documentation, photographs, drawings, and sewing instructions focusing on period construction methods, but can be sewn using modern sewing machine methods. The person who buys any one of these patterns can be confident that the pattern shapes are period correct which allows the individual the option to be as period correct in sewing techniques and construction as he or she wishes to be.
