Today’s invention is for kids who are learning to dress themselves (or even we absent-minded grown-ups).
Shirts and blouses would have a few coloured stitches added to each button and buttonhole.
One button would have eg red thread and its corresponding buttonhole would have a few of the same colour stitches sewn in.
In this way, it would be much less easy to get dressed with buttons and holes misaligned (thus avoiding significant parental distress when having to undo everything and start again, every day for six months).
