This book shows how corsets changed to fit well under clothing, give maximum support and comfort. Corsets pushed up breasts and showed off the bust line beneath a square-cut and low-cut neckline as in the early 1800s, or Regency years. Jane Austen and her female and friends wore these corsets. Corsets or stays worn during the early 1800s, or Jane Austen’s lifetime. https://books2read.com/SuziLoveCorsetBook17

The main purpose of corsets was to support and shape the breasts. Though they still slimmed the midriff, this was not the prime purpose of a corset between 1810 and 1830. The waistlines of dresses were lowering to below the bust line but nearer to the true waist, so corsets were longer and were given added shaping by stitching and cording and by shaping the breasts with pleated or gathered cups.
