Ok, no responses, I'll post my own experience. I completed this last night. I went with black drawstring nylon soccer shorts and a short tye-dye t-shirt that stopped about 2 inches above my shorts, hoping to appear I just came from a workout. I went with flip flops. The shorts I left untied and strings hanging. I felt confident the shorts were not going to slide down any, but they were probably low enough to call into question whether or not I was wearing underwear. I was obviously out of place because
it was soo cold! I ran into one couple that wanted to talk; they said they enjoyed having fun too. Probably should have engaged them more, but I was freezing! I gathered up a large load, and headed to the car with the basket. It was quite interesting getting the basket rolled to my car in flip flops because we still have snow on the ground. I took off the flip flops, loaded the car, and took the cart back, over an aisle but not far away. I raced back to my car because my feet were freezing by this point. This was quite fun, and I'm sure the employees who were glancing at me as I shopped are talking about me today.
