These rare Regency ladies’ jumps or waistcoat, dating to ca. 1795–1800, represent an important transitional undergarment between the structured stays of the 18th century and the softer silhouettes of early Neoclassical fashion. Jumps were significantly less boned—or sometimes entirely unboned—than traditional stays. They provided gentle bust support without shaping the torso into the rigid cone typical of earlier fashions. Because they closed at the front, they were far easier for a woman to put on and remove by herself.

Originally worn for informal dress at the beginning of the 18th century, jumps remained popular throughout the century as a comfortable alternative to stays. Their use increased dramatically toward the end of the century as fashion shifted from elaborate Rococo styles to the soft, flowing lines of the Regency and Directoire periods. As jumps gained popularity, other soft undergarments—most notably the early corset—began to evolve alongside them.

This exceptionally well‑preserved example is made of brown brocade silk with a floral motif. It features a front button closure (the buttons have been replaced) and retains its elegant, lightly structured form. The garment is in very good condition, with only minimal signs of age. Decorative accessories shown in photos (blouse and jewelry) are not included.

A small size, this piece is a rare and valuable survivor from the late 18th century—highly desirable for collectors of Regency fashion, historic undergarments, and museum‑quality textiles.
