you seem like a person who might know where to find some good resources on undergarments of the 1820s 👀 no reason (fanfiction reasons)
You are correct! Here are some 1820s stays for you:
(all from the MFA Boston, 1, 2, 3.)
Note their common features: a very wide horizontal neckline, gored bust cups, back lacing, cording rather than boning, and a busk down the center front.
This would be worn over a shift or chemise, made of linen or cotton, and under several petticoats. This post has a bunch more examples and a detailed breakdown, although it’s focused on the later 1820s/1830s. They also have an example of stays with fan lacing, so go look even if that’s later than you need because those are cool.
