I agree that some people need to care a little more about their appearance and not go out looking like slobs. However: I do upon certain occasion's wear pajama pants to Walmart if it's after 12 am and I have to get my children medicine, myself or my husband.

Fashion isn't always a priority. Sometimes it's more appropriate to wear normal dress attire but I hardly would classify someone as a slob for trying to be comfortable if it's the middle of the night and they need a couple items from Wally World. Besides, come on now, we are talking about Walmart, not Macy's.
