You're excited, so you say, "I'll take it."
You expect the shopkeeper to wrap it up, but instead he pulls out a wand with a glowing tip. He taps the suit, and then he taps your shoulder. For a brief moment, you feel naked, and then suddenly the snug suit hugs your body. The lights on the suit are flickering in time with your heart rate now, and damn it really is skin tight. You can see your nipples through the snug fabric, and not wanting to look, you're sure your buttocks and manhood are totally exposed in equal detail.
"Uh, where are my old clothes?" you ask uncertain about what just happened.
The old man reaches behind the counter and pulls out a brown paper bag. He hands it to you, and you glance inside, all your stuff appears to be there, and neatly folded at that. You feel your suit, and notice it doesn't seem to have pockets. You look at the man, who is staring eagerly at you.
"How does it fit?"
"Like a glove, but it doesn't have any pockets. Where am I supposed to put my wallet, and keys, and such?"
"Ah, if I might show you?" he asks. You nod. He reaches for your waistband, and tugs it forward. You look down, you're not sure if from his angle he can see your privates, but from your perspective you can. You also see a tiny pocket like you might find inside running shorts or a swimsuit. Big enough for a key, and maybe an ID card, but not much more. He lets your waistband snap back.
"Not big enough for my wallet," you lament.
"Oh, but it is. It's a magic pocket. You can even make your clone climb inside it for storage, if you need. You know it's bigger on the inside than the outside, and from the outside it's invisible."
"Oh, okay?" you say digging your wallet out of the brown bag, and trying to put it into the hidden pocket which is only half as big. You blink, as the wallet vanishes into the pocket. You run your hand over the front of your pants, but there's no bulge or outline. You open the hidden pocket, and reach in, and easily feel your wallet. "Wow!"
Now you're really excited to try out the cloning features. You glance at the old man, but since he has a wand, and this is his shop, you think he might be able to resist the suit, and maybe hurt you in the process. So instead of using it on him, you say, "Thank you." Taking a step toward the door with your bag, you hesitate about going outside in the costume. You turn and ask, "Maybe I should wear my clothes over this suit? I, mean, the suit's rather - uh, unusual."
The old man laughs, "Oh, I forgot to tell you about the glamour feature. Touch your hand to your right shoulder, and imagine what you want to be wearing. The suit will appear as you want it, but the pockets, buttons, zippers or whatever will only be an illusion. You still need to use the hidden pocket to carry things."
You look at him curiously, and raise your right hand toward your left shoulder.
"Right shoulder not left. Left shoulder turns off the glamour," the old man explained.
You touch your right hand to your right shoulder. You don't feel like your clothes changed, but you look down, and it looks like you're wearing the clothing in the bag. You reach for the side pocket, but you hand slides along what feels like smooth Spandex instead of cotton twill.
"Sweet!" you say, and open the door to the street. Looking over your shoulder, you say, "Thanks, again."
You step out onto the sidewalk, and immediately, a skateboarder plows right into you. You catch yourself in the door frame, but he ends up on heap in front of you. You glare at him angrily for a moment, and then smile, you found your first slime clone test subject. You activate the suit.
The skater's face glares up at you, but then it goes blank like he's in a trance. His skin is all shiny like he's coated with petroleum jelly, but then his blank expression is suddenly your face with a blank expression. You reach down to help him up. His clothing hasn't changed. He was about a head shorter than you and a bit thinner, but now the loose skater shorts fit tightly around his waist. His shirt exposes your belly, as it rides up his now longer torso. You glance down at his feet. His shoes are covered with oozing slime. You realize your feet are bigger than his. You order him to remove his socks and shoes. It's weird you can see his smaller bare feet covered with slime. Then the slime flickers and expands, and his feet are gone. In their place are twins to your bare feet.
"Hm?" you say looking at his shoes and his bare feet, and then at the hot sidewalk. You look back at him, and think. The old man said he could modify his clone.
You ask, "What's your shoe size?"
The clone answers in your voice, stating your shoe size.
You frown. Then ask, "What size are these shoes?" You point at his old empty shoes.
"Size 7," he says.
"I wish your feet were now size 7."
You watch as his feet shrink to their former size. You smile, as they are still your feet. Your second toe is the same length, as your big toe, but you noticed his second toe was longer than his big toe. His shrunken foot the big toe and second toe are the same length.
"Put your socks and shoes on. Pick up your skateboard, and walk behind me," you command. You smile and carrying your brown paper bag begin to walk up the street. You stop and glance over your shoulder, he is three paces behind you. You glance down at the bag. And say to your slime clone, "Carry this too." You hand him the bag. You start walking.
