A dandy’s toilette (1818). A colour engraving, alas the artist is unknown. Used in the book: The corset, A cultural history by Valerie Steele.
The dandy, might be George “Beau” Brummel (1778-1840), an iconic figure in Regency England and an arbiter of men’s fashion. He was a friend of the Prince Regent, the future King George IV.
