As a wealthy gentleman in the Regency era, Mr. Darcy from "Pride and Prejudice" would have worn impeccably tailored clothing reflecting his high social status and the prevailing fashion trends influenced by Beau Brummell. His typical attire would include a dark, well-fitted tailcoat (likely in blue, green, brown, or black), a lighter-colored waistcoat (perhaps silk or embroidered for evening), high-waisted pantaloons or breeches, polished riding boots or dress shoes, and a starched white linen shirt with a meticulously tied white cravat. His clothing would emphasize clean lines, quality materials, and understated elegance rather than excessive ornamentation.
