Tough call for women/female-identifying clothes wearers. The most sartorially impressive female clothing, confined to economic elites, has usually also been the most cumbersome and impractical. Because dressing impractically is one of the ways to show off how economically elite you are, obvs.
I think to maximize both luxury and comfort, I’d go for some of the 1920s styles in western fashion. You get fine materials and opulent embellishment, combined with less restrictive garment styles and lighter underwear. The straight silhouettes are not particularly flattering on most people, though.
Alternative: The “Turkish trousers” or various salwar-kameez type outfits worn by women in a lot of medieval to modern West, Central and South Asian cultures. Great fabrics, super comfortable cuts, more flattering shapes than your ‘20s sack dress.
Indian sari/choli is in my view the single most beautiful and elegant style of female dress known in human history, and not far behind the leaders in wearability/convenience once you know how, but a floor-length undivided skirt is always going to lose convenience points.
If luxury’s off the table, then various working-class women’s garb from any number of cultures will do. Extra points for including some form of comfortable, secure and becoming hair restraint/head covering. Sample candidates:
Early modern European “peasant costumes” of smocked white blouse/shift, jumps/vest, above-ankle petticoat and skirt with colorful apron, gartered stockings, flat shoes, head cap.
Modern pants or leggings with top and jacket or vest is almost as good, but usually not such a cute shape, and no conventional hair restraint unless you do baseball caps.
Rosie-the-Riveter style boiler suits or shirt and overalls with headscarf and flat boots is utilitarian but perky, I would happily wear that to work every day. Needs some kind of crotch accommodation for toilet use tho plz.
I have never worn a traditional East or Southeast Asian workwoman’s jacket-and-trousers with headwrap and sandals or slippers combo, but they look very wearable and practical. More drab on average than European peasant counterparts tho? Or was that just the Communist versions? Bring on the sashiko and patchwork and tambour embroidery thx.
