TL credit page is right, "Sexiled" is an awful name. I didn't connect that this was that story until reading the credits.
Maybe, but on the other hand, that title did wonders for the marketing of it. The more literal titles are pretty generic (and unnecessarily long) and would not have garnered nearly as much attention.
Anyway, I don't want to go too spoilery (I've read the novels), but for those wondering about what she's wearing, she won't be wearing it for too long, and it does have an in-universe justification that fits the themes of the story.
And yeah, this series is pretty unashamedly heavy-handed in its gender politics. It didn't bother me, but if it bothers you, I wouldn't recommend it. No, what bothered me were the yuri being much lighter than expected and a particular...something at the very end that I naturally can't talk about yet. The manga may do both of those better, though.
