I made my costume first (in a hurry!) from a black hoodie dress and some fake fur (on sale!). It cost me about $10 to make (since I already had the hoodie - wore it all winter last year). I got the idea from here: http://www.craftster.org/forum/index.php?topic=324788.0
I won the costume contest at my office last Friday. I used plastic grocery bags to stuff the tail which made it really light - I didn't get a chance to take a photo of the tail, though.
I made my boyfriend's hat using the leftover fur. You can't tell in the picture, but it has black ears. I also made him some mittens with scraps of fur. He didn't decide until about 4 hours before we were going out what he wanted to be. I wish we had more pictures, but this was a picture that was taken at the bar by a friend.
I'm on my work computer and so I can't edit the photo at all, thus the horrible redeye. Sorry!!!
I'm too new to post pictures, so I posted the link to the picture. I used to have an account here a few years ago, but I forgot the password.
