The girl perused the shop's aisles, seeing more kinds of costumes than she had even expected, yet none of them seemed the right one. She was browsing a rack of plain full-body jumpsuits when she came upon a plain black number. Pulling it off the rack, she saw it was a one-piece spandex suit, apparently form-fitting. It not only had sleeves for the arms and legs, but "gloves" and "socks" for the hands and feet. Looking at it more closely, she couldn't find any seams or openings in the fabric, except at the neck. It was all one human-shaped piece. How could someone even put it on?
She brought the suit to the front counter, where a plain-looking man stood at the register taking inventory. Upon posing her question about the suit, the man explained that it was made from a special synthetic fabric that could shrink or expand to fit any person, large or small. He welcomed her to try it on.
Although the outfit was unremarkable for its design or attractiveness, the girl had to see this for herself. She went to the changing room and undressed down to her bra and panties. Then she took the bodysuit and stretched the collar to remove the hangar. Being told about the fabric's elasticity was one thing, but seeing the neck open so easily for the entire hangar to come out made her gasp. She dropped the hangar on the floor and, with both hands, stretched open the collar. It opened so easily, like putty, yet once she had stopped opening it wider, she felt it gently trying to pull itself closed just like spandex.
She sat on the changing room bench and lowered the three-foot-wide collar to her calves. She slowly slipped her legs into the suit, feeling for the leg holes. She pulled the suit all the way up her legs, feeling the smooth material hug them tightly.
She stood up and began to roll the rest of the suit up her torso like pantyhose. Once it reached her armpits, she slipped one arm in and watched it fill the limp sleeve. The thin fabric fingers at the end of the sleeves bulged to proper size as she tugged the suit up her shoulder. She repeated this step with her other arm, and once it was done her collar automatically closed itself around her neck, covering her from the chin down in a seamless spandex "stocking."
Apart from the toes being bundled together like in socks, the bodysuit had formed to her body exactly. There were clear impressions in the suit that matched the shape of her panties and bra. She could even see a dimple at her navel. Her fingers felt as flexible as if there were nothing covering them at all, and she seemed to have that same ease of mobility throughout her body, minus an almost imperceptible tug of the spandex continuously trying to tighten itself to her skin.
She was so fascinated by this suit she made the decision then and there to buy it. She wasn't yet sure what she could do with it, but she was sure an idea would come up. Since it was perfectly fitted to her, she saw no point in taking it off. Instead, she threw her clothes on over it with no difficulty. The only areas of the suit that were visible now were the hands and neck. To a casual observer, it would merely appear as if she were wearing black gloves and a collar.
She stopped at the register to pay for the suit. The man wished her well, and mentioned that the suit had a few other special qualities she was sure to discover in time. When asked about these details, the man simply said they differed depending on who was wearing it and could not speculate on what they'd be for her.
A bit puzzled, but still pleased about her purchase, the girl left the shop for her next destination.
