I love them they are so practical . I remember the days when all shirts had to be pulled over your head but now I believe all shirts are fully buttoned , maybe ordinary pullovers will go the same way and we will all be wearing practical cardies.
Maybe everyone ought to wear boiler suits and be done with it; no messing about, deciding what to wear against what; no hunting round for a clean shirt; easy to wash and dry; no jealousy that someone's wearing better clothes than yourself...
