Can someone explain men's fashion in the 1810's in a brief summary?

Both breeches and pantaloons were worn during the 1810s. Breeches extended to the knee where they were fastened with buttons and a buckle or tie (Fig. 1); pantaloons, which had originated in the 1790s, were very tightly-fitted and longer, extending to the calf or ankle where they fastened with ties or buttons (Fig. 4)(Byrde 93; Johnston 14). Either could be worn during the day, but breeches were the proper evening attire with white stockings and evening pumps (Fig. 5). For daywear, both were frequently worn with tall boots, a favorite fashion of early nineteenth century menswear (le Bourhis 112). It was particularly in vogue to wear pantaloons tucked into “hessian” boots, defined by heart-shaped tops and tassels (Laver 160). Named for the Hessian mercenary soldiers from Germany, these boots and clinging pantaloons, which displayed a man’s leg muscles to great effect, lent a martial glamour to civilian dress (Ashelford 186; Johnston 14). The man in figure 1 of the Womenswear section sports pantaloons and hessians.
