...which I based after this cuff from the V&A. (It's on p.94 of Seventeenth & Eighteenth-Century Fashion in Detail).
c.1770-1780 Cuff from Printed Cotton Caraco
Istead of adding the "cuff poloniase" I made little pleats as seen in the example below.
Winged cuff from woman's bodice c.1740s
Having a limited supply of buttons, I used them for the back so I could polonaise the skirt.
Overall I think the gown turned out fairly well.
