I made some tail myself, too. and I usuually wear it. but I dunno why, but people in my school just makes a big fuss about it. but I still do. I also wear a dog collar.
tip of making a tail: first, measure how long you want it. Then, buy a fabric thats about that long. Also, buy a chain thats the same length. cover the chain with the fabric and sew it well together (smaller you sew, less obvious the sewing line, and try doing cross sewing, for a nice firm closure, so it won't open). Last, you get 2,3 safety pins, and pint the very top of the chain and the bottom of the chain to keep the tail up.
You do this, to give your tail some weight and to make it look some what more realistic movements. and also, even if you sit on it, it won't get flat.
thats how I made mine :3
and I also made an arm warmer glove with fabric, too :3
