I just thought they were novelty items more than something people would actually put on their hamsters for longer than the time it takes to take a photo.
But I suppose you have to look at it from the point of someone who doesn't know about hamsters.
My minature poodle who has long passed over the bridge used to be dressed in my dolls clothes and taken for a walk in a pram. I am cringing now, but I was early primary school age.
I also had a lop eared rabbit called fresia who I used to regularly take walks on a harness and she had a wooly jumper and a small waxed coat for when the weather was bad. That I have no excuse for, I think I was about 2o at that time
