Quite well, though someone gets curious.

"So, if we carry the one here..." Tooru murmured as she focused on the study material, when she noticed several of the group staring at her. Nothing she wasn't used to, being invisible and essentially occupying a floating set of clothes did tend to turn heads, but she was still taken aback, since these people had known about it for about a week. Trying to undercut the tension with humor, she asked, "What's the matter? Haven't you guys seen an invisible girl before?" she laughed, waving her hand in front of her face with a chuckle. "I mean, I guess not, but you know... What... I..." she trailed off, staring at her hand... Her perfectly visible hand.

"What the!?" she yelped, running to a mirror, and staring at her reflection. "...I'm... Visible?" she asked, staring as she ran a hand through her messy, vivid, yellow-green hair, which had some pink highlights.

"You mean you couldn't turn visible before?" Kirishima blinked.

"No, I couldn't!" she shook her head, and then tried to focus on being invisible again. She shimmered, and faded from view, her clothes the only visible part once more. "Wow! This is neat!" she added, turning visible again, then back to invisibility, this time causing her clothes to also become invisible. "Whoa! I can expand the invisibility too! Nice! Now no more needing to get naked to be fully hidden~!" she cheered.

"Your Quirk must have evolved, or something!" Ochaco said cheerfully. "It's a Mutant Type, right? Those do that sometimes!"

"Must have!" Tooru agreed. She turned back to the group, and turned visible again... Then paused when they all mostly averted their gazes. "What?" she asked, before looking down. "...Eeeek!" she shrieked, covering herself as her whole body was visible, but her clothes remained invisible, making her look naked. She had been naked around others before, but she had been invisible then! A bit more focus brought her clothes back into view as she blushed furiously. "...I... Am going to need to practice this in private before I do that again..."

"...good thing Mineta didn't accept the offer to join the study group..." Mina giggled a bit.

This got a laugh from everyone, though Izuku whispered to Momo, "Did you give her somewhat spotty control of her ability to make things she was touching invisible or visible again on purpose so that would happen?"

"Yes, why?" Momo asked quietly.

"Not cool. She didn't consent to being seen naked," he chided her in an undertone, and she looked sheepish.

"Sorry, Master, I sometimes forget other people still have boundaries, given I lack them..." she apologized.

"Be more mindful of that," Izuku muttered firmly.

Jiro meanwhile looked intently in their direction the whole time they were whispering, before discreetly returning to studying.
