I had a pair of bada$$ red velveteen pajama bottoms I used to wear out all the time. They didn't necessarily look like pajama bottoms, though. I wear mine to walk the dog sometimes, but wouldn't wear them anywhere else. I have seen a few people run into the local Co-op in their jammies if it's late at night. I had seen many people in America walking around in house robe, slippers, and hair curlers at the grocery store, which always made me laugh.
