What do you wear in the garden?

I can't understand you folks who go out to the garden in untidy clothing, it should be a suite with waistcoat and highly polished boots or shoes Well that's the way I think my OH wants me to go out, twice I have had to remove my favourite jumper from the bin and I get glowered at when I put it on, but I am comfortable in it and there are that many stains on it, she doesn't know when there's a new one
