Dressing a 1790's Gentleman

Or, "Dressing Mr. Darcy".

1) The model, 2) leggings and loose fitting undershirt with a tall stiff collar, 3) breeches and cravat, 4) waistcoat and boots, 5) tailcoat

This is part of a series that I'm doing, using nude figure drawings from class as models for historical fashion. This is my first time trying men's fashion. I thought it'd be simpler but there isn't much historical information on men's undergarments. Anyone is welcome to jump in with corrections or to suggest that something is missing.
