I've realized that I have something of a dearth of basic eighteenth century garments. I've made myself a proper shift using my best stitches, and a basic underpetticoat - just a rectangle pleated and attached to a waistband. For my shift I'm indebted to the Danish Natmuseet for their pattern, which I used as a general guideline. I cut the neckline a little large, so I ran a tape drawstring through it - not the most common neckline treatment in the eighteenth century, but not unusual.
