I would have you dressed in a T-shirt, sweatpants, and some black ankle socks. I would first tie your elbows together with some rope, to keep your hands closer to each other. Then I would put crew-length socks over your hands and secure them with some tape at the wrists, and top it off with one ankle sock over your hands, so it doesn't go too high up. I would then tie your wrists and forearms and move on to your legs. I would tie your ankles, calves, above and below your knees, and maybe your big toes, right through the socks, if you move them around too much

Of course, I can't have you talking, so I would shove some worn ankle socks in your mouth, put one sock over your nose, and put a stocking over your head to keep all the socks in. That wouldn't be enough to keep you silenced, so I would wrap plenty of duct tape around your mouth and eyes. To top it all off, I would add some crotchropes and tie your hands to them, so you wouldn't feel to compelled to move around a whole lot
Let me know what you think.
