You are welcome to rant...
Personally I'm not too bothered what people wear...after all clothes purpose is to give one's body a 'shelter' against elements.
Just a pieces of fabric sown together that are given different names for their intended purpose for wearing.
I'm not too upset neither should somebody not wear nothing at all.
But, I suppose when we live in society where certain way of dressing up is 'norm', one should try one's best to be acceptable.
I have to admit that some 'night wear' materials are really nice and comfy..been tempted myself many times not to bother with 'proper' clothes and carry on the day in my PJ bottoms..
Edit to add...my mum has fleece 'bed jacket' that she has worn as kind of 'cardie' when going out...only give away for its true purpose was little teddybear motive on breast pocket..and nobody haven't really noticed it at all
