Temple of Ranma's Sailor Senshi Seifuku

Cloud Dreamer did that in a couple of his fics, but the only one I can recall off-hand is the one where Skuld locks him in female form and she eventually winds up with a bracelet that repairs and improves any clothing the person is wearing to be top quality. Except that it only does female clothes because Ranma is currently female (or possibly only does female clothes, she's still locked at this point and I don't know if they addressed it when he finally was ale to change back). Only trouble is that it was really girly clothes. Anything she wore while wearing the bracelet got turned super girly, but high quality.
Oh, and the person who gave it to her forgot to tell her the password to remove it, so Ranma was stuck with it for several days.

Oh, and as for the original request, I believe this qualifies:

Princess of the Moon reviews
Permanently cursed to be a girl at Jusenkyo, Ranma does't take it very well and sets off on her own after punishing Genma. This story has a lot of twists and turns, so one can never be sure exactly what will happen as Ranma influences everyone.

I recall another one where Ranma got the mantle of Serenity, and the body. IIRC before it was abandoned she wound up on the Moon where she could do simulations on how to uplift society with the help of an AI (the same hologram that greets the Sailor Senshi in that one episode where we get the exposition on the Moon Kingdom). Everything she did wound up in failure. Then, getting tired, she decides on a whim to try one thing just for the heck of it, not trying to be serious and sets the simulation to create a religion on her being a god. It succeeds.

TY for all the links I also found a Media Miner story that didnt go far and fits. Paternity of a Princess https://www.mediaminer.org/fanfic/c/sai ... 809/590298

Saturn shook her head and said, “Sailor Moon, I think you'd better take a look at her. She has come kind of magic on her that I can't touch. It seems to be affecting her body.”

The blonde leader of the Senshi stepped up and grasped the Silver Crystal. Its light shined on the redhead and Sailor Moon listened to the information the crystal was giving her. She finally said, “I don't know what the magic does, but she's had it for some time. I'm not sure if I should try to remove it. It doesn't seem to be affecting her health.”

Tuxedo Kamen asked, “Could it be some kind of mind control?”

Sailor Moon knew enough to recognize magic when she saw it, but lacked the training to understand what the magic was doing to the girl. She answered her boyfriend, “I don't know. I suppose it's possible, though if it has some influence on her mind it's too subtle for me to see.”

The Senshi leader was starting to think it might be best to wait until the girl woke up before doing anything about the magic. That way they could ask her if she knew about the magic and what it was there to do. Before she could voice this opinion her boyfriend said, “She saved our lives and got hurt doing so. We owe it to her to help her in every way possible. Please, Moon, help her.”

Firming her resolve, the Moon Princess took hold of her power and began the effort to free the girl from the grip of the magic. It was not easy. After a moment she said, “I know what the magic does. It's some kind of shape shifting spell or curse. When I try to remove the curse it tried to change her shape before it leaves. All of you join your power to mine. I need you to hold her shape like it is while I remove the curse.
