Medieval women's tunics were either floor-length if nothing was worn under them, or at least knee-length if a skirt or under-dress was worn beneath it.I like the skant uniform, albeit with proper leggings and boots. If done right, it has a futuristic-take on a medieval tunic.
None of the gown-clad Vulcan women were working on starships. Gowns would be completely impractical for on-duty garb, regardless of who wore them.T'Pol was particularly odd because all other Vulcans wore gowns![]()
Q did the hat-wearing in TNG. Kirk and Spock wore hats if required to fit in with the natives when they were on various planets.The most egregious starfleet uniform sin is the lack of hats.
