For a more 19th century look, I've always been a fan of the androgynous look of the 1830s (When feminine looks were hyper-feminine to compensate)
Tight, steel corseted jackets with raglan shoulders, pleated pants for wide hips, 2.5 inch heeled Chelsea Boots (Elastic sides, very-modern!) and burgundies, dark greens and blues, russets, plums, and loudly coloured check pants.
Obviously that stuff is hard to find or even sew today, given you need the skills of both 18th century and modern tailors to make the jackets. But you can lean into an archaic shilouette and raid both gender's racks at the store to gesture towards earlier, less rigid style languages.
