Go half-in, and have them be your legs

"Maybe, uh, we can ease into this idea of wearing anyone as part of myself? That's a lot to take in... any way to slowly wade into these waters?"

You felt like all of this new information was hitting you like a freight train, and the idea of putting on someone else's entire body was a bit suffocating, figuratively at least.

While Zoe seemed a bit stumped by your request, Chloe gave a thumbs-up. "Easy, what about... half-wearing us? If I could make it so Zoe was just legs, would you do it?" This caused Zoe to blush furiously by the idea of being reduced down to only part of herself, but she remained quiet as she looked towards you. Any opportunity to make you more comfortable with the idea was one she was at least willing to entertain.

Your shock by the idea took a bit to subside. "You can just make her do that? Wouldn't it kill her?"

"You forget that we don't operate on the same kinds of physics as normal humans!" Chloe was quick to cross Zoe's arms, eyes locked on yours. "Zoe exists in some weird upper dimensional space, what you see before you is essentially a three dimensional 'slice' of her on the outside, which is different from the inside, which... it gets complicated. So even if reduced down from what you see, the majority of her still is intact and functioning normally. That's also why you'd be able to wear her and she could be flush with your flesh, no extra bulk or anything while I'm also still present in her. You'd just look like you'd have normal legs."

None of that made much sense to you, dimensional shenanigans were above your pay grade. But you shrugged all the same. "If you could make it that I could put on some clothes and finish out my workday without anyone noticing, then... okay. I'll try just some legs."

Zoe smiled. "I suppose I'll go along with it, then. But, consider that you're going to be wearing my legs in my shape, so it's going to be my cute butt you're going to be sitting on all day. You'll want to wear my pants instead of yours, they'll fit much better."

It seemed a small price to pay, having to don some new attire. Hopefully it wouldn't cause much of a stir under a labcoat...

Chloe didn't wait any longer, as Zoe's upper body seemed to just start fading away, falling into itself. Her head and arms began to retract, leaving large holes around where her former limbs would have existed. Her body sort of looked like suspenders--maybe that would be a good next step to getting used to wearing her body? But your thought quickly was lost when her upper body began to sink down as well, until Zoe's body was nothing more than what she had from the waist down, with Chloe's face still present. Chloe didn't seem to have any trouble walking herself over to you, as she climbed up onto a chair to stare her face into yours, as you looked at her legs.

"Well, isn't this fun? Zoe's a bit of a captive at the moment, and maybe instead of being worn, you'd want to make out with half a body? I can still do quite a bit with just these two legs, you know..." Chloe winked at you, teasingly.
