In truth, in the 90s I owned a cheap Santa suit. I got it from one of the many struggling costumers in the Theatre District. I opted for purchase since it was actually cheaper than renting a good one. It even came with these slip on things to make your shoes look like boots!! The only thing I splurged on was the hair and beard.
I used to wear it in the AG's office for the holiday parties.
My cats wouldn't be patient enough to wear anything. They don't even have collars.
I tried not to sit too often in the suit. The clerical women of the office used to want to sit on Santa's lap. Many of them out weighed me.
