Dylan decided to go with a classic. An elegant fox tail. He picked it out of the pile and examined it. The details were pristine. It was like looking at an actual fox tail. However, he didn't seem to see a belt, clip, or anything that would attach to his pants. It did say costume in the title after all, so it must attach some way. "Huh. So what do I do with this? Tape it to my backside?" Dylan held the fox tail against his rear. He thought to cram it against his pants to hold it together. To his surprise, it worked pretty well.
