Have them strip first.

"Well Lucy, seeing as you don't have a maid uniform, you should get naked instead," Natsu said, and Lucy blushed.

"O-okay Master," she said hesitantly. Natsu grinned at how cute she looked. Unlike the **** persona, who eagerly did anything asked, the maid persona would also do anything asked, and like doing it too, but would have more inhibitions about it.

As Lucy opened her blouse, Virgo asked, "Shall I join Mistress in nudity Master? Or should I give her my uniform?"

Natsu chuckled. "That's true, you are lower on the ladder than her, so it's only fair you're naked too. Put the frill on Lucy though."

"Understood Master," Virgo said, taking the frill off her head and putting it on Lucy's as she worked on her skirt, before she got to work on removing her own blouse.

Lucy looked up at Natsu cutely as she slid her panties down, and stepped out of them along with her shoes and skirt. Now naked except for the frill, she stood, covering her breasts with one arm and her pussy with a hand, smiling despite her red face. "Is this better Master?"

"Almost, move your hands," he said. She whimpered, but complied. "Good girl," he told her, getting a smile from her.

By this point, Virgo had stripped naked, and stood without a care in the world in contrast to Lucy. "Is my body also to your satisfaction Master?" she asked matter of factly.

"Yes, yes it is," he told her, giving her the thumbs up.
