I am not female, so you may want to disregard my opinion, but I feel the need to leave it here anyway. I find a lot of it appalling. Unless there's a subtextual or satirical joke running through part or all of the show, there is no reason for a school's uniform to comprise of miniskirts, kneehighs, and borderline formfitting sailor uniforms. One anime that handled uniforms really well was Shimoneta (an anime about censorship and embracing but not overindulging in one's "less pure" thoughts), where skirt length was indicative of one's apparent personal purity. This was never openly stated in the show, but rather was implied by the fact that the leader of the dirty terrorist group SOX had a much shorter skirt than the class president (among other comparisons that would take too long to go into). Another show that handled uniforms well was High School of the Dead, which was a blatant satire of ecchi while also being one.
If an anime is trying to be taken seriously, though, it really needs to take its character and clothing design seriously. In Fullmetal Alchemist, Winry Rockbell wears a tanktop at work because she's a mechanic, but whenever she travels she switches to a coat and an admittedly kind of short skirt, but not obscenely so. Many women stay in uniform throughout the series as well, such as Olivier Armstrong and Riza Hawkeye, who wen nto in uniform is wearing a pretty thick black tee and pants.
Shows that take themselves seriously but disgust me in terms of clothing design aremuch too common though. Sword Art Online has a ludicrous amount of ass and camel tow shots, upskirts, and revealed sections of torso (despite being set in three worlds that would all require the torso to be covered) without any good explanation other than "This is a wish fulfillment anime for 14 year old nerds". Asterisk War, Gate, and many other anime suffer from the exact same issues for the exact same reason, which may be why they get so popular among the 13-25 male demographic. They're pandering, pure and sumple, to the fantasies of guys who feel trapped by a society that tells them they're nothing special, they shouldn't even think about sex until they're married, adventure isn't real, and normal people never matter. That veered off the main topic a bit, but my point is, the bizarrely underdressed female characters are a staple of pandering anime.
Weird side note: the other half of the 13-25 demographic watches Steven Universe, Gravity Falls, and Adventure Time.
