Yes, but Dorothea has a take on that

"Why not give your harem members some sexy uniforms~?" Sothis purrs at Byleth. "Wouldn't an entire party of sexy girls dressed like me be to your taste?" She moved her formed legs sexily to give her body a sexy jiggle as she posed on top of Dorothea for him. Honestly, Byleth did think that had potential, but...

"Ahem!" Dorothea raised her hand, shooting it up past Sothis's head so Byleth could see his student's interactions. "I don't mind the idea of uniforms, but I object to the idea of them being the same as each other."

"...dear, that's the definition of uniform." Manuela corrected after a chuckle. Dorothea managed to get Sothis off of her by groping the genie's breasts with a push, the green haired girl moaning as she's moved aside. "What I meant is, if we do end up getting sexy harem outfits, I don't think they should be identical with just differences in color." She clarified. "If we're all just dressed the same, wouldn't the outfits be just boring after a while? I feel like we should be allowed to be able to make some small modifications to our own outfits." She finished, before remembering her new position. "P-provided Professor Byleth approves, of course!" She stammered out, bowing her head as she did so.

"What Master says goes~" Sothis rose up and gave Dorothea a playful smack on the ass, Byleth pondering. "Hmm, that does sound interesting... Manuela, what do you think? He asked while Sothis and Dorothea had begun erotically play fighting with each other.

"Well, I do think that the head of the harem should get what he wants~" Manuela said, crossing her arms beneath her impressive chest to bounce them for him. " But I can see Dorothea's point. There are plenty of students who made modifications to their school uniforms. Dorothea added a hat to hers, and both Leonie and Raphael don't bother with the outer shirt of their outfits. Mind you, in the latter's case, I don't think they have any outer shirts that could fit over those massive muscles of his." She said, Byleth coming to his conclusion.

"Okay. Sothis." Byleth returns his attention to his genie, who was currently trapping Dorothea between her boobs, the new student tweaking the genie's nipples in an effort to escape. "I wish that members of my harem could slightly alter any harem outfits - or costumes - they receive from a wish at will. And also give them the harem outfits, and let them change between that and whatever they were already wearing at will when alone with just other members of the harem."

Sothis snapped her fingers between moans as Dorothea escaped from giving the possible god an orgasm.
