If fashion on the shows reflects society then SNW is downright conservative in the way the females dress.
1) "Females?" Really?
2) It's not that SNW is "conservative" in the way women dress. It's that SNW is not sexualizing them. There are times when women characters dress in ways that are sexual when it's appropriate for their characters -- Christine's tight dress for her date in "Spock Amok," T'Pring in her underwear in the pilot and in a somewhat-revealing wedding dress in the dream sequence of "Spock Amok;" La'an wearing a very cleavagey dress as her princess character in that late S1 episode whose name I can't recall. But they're characters who aren't, y'know, going out to nightclubs trying to get laid all the time, so they don't dress sexually. That's neither conservative nor liberal.
