I am yet to find anyone look attractive in a pair of craghoppers.
My apologies to the percentage of the forum who might be owners of such trousers, but I feel quite strongly about them. This may or may not be connected to previous bad experiences with a geography teacher and fellow artificial intelligence students. But anyway, I would counsel against such leg wear.
While I can’t speak for the OP, I can confirm that looking attractive is quite low on my priority list in general for knobbing about in the garden.
Oh, and as someone else said, a boilersuit is the business for this type of thing. At this time of year, one of the quilted or insulated varieties depending on exactly how chilly it is.
