The shift, chemise (in France), or smock, had a low neckline and elbow-length sleeves which were full early in the period and became increasingly narrow as the century progressed. Drawers were not worn in this period.
The long-waisted, heavily boned stays of the early 1740's with their narrow back, wide front, and shoulder straps gave way by the 1760s to strapless stays which still were cut high at the armpit, to encourage a woman to stand with her shoulders slightly back, a fashionable posture. The fashionable shape was a rather conical torso, with large hips. The waist was not particularly small. Stays were usually laced snugly, but comfortably; only those interested in extreme fashions laced tightly. They offered back support for heavy lifting, and poor and middle class women were able to work comfortably in them.
Woolen or quilted waistcoats were worn over the stays or corset and under the gown for warmth, as were petticoats quilted with wool batting, especially in the cold climates of Northern Europe and America.
