As long as these are the worst "offenses" some people commit - I think we should thank them for giving us something to talk about!!
I really don't mind if someone shows up in a hardware store, garage, plant nursery, etc - in work clothes that may be dirty if they are in the middle of a project and need to pick up parts or supplies for whatever they are doing.
I do mind - a lot - if someone is planning to try on clothing and they are not "fresh as a just-opening-up daisy!"
But I do agree - some sights are less attractive than others. The one that bothers me is the T-shirt that is too short to cover a very big, very protruding belly. (Usually seen on a man wearing sweat pants or elastic waist shorts.)
