I always loved what I call 'courtesy' tailoring: the spare buttons on the inside, the easily unpicked and resewn hem, the bra-strap tie on an evening gown, etc.

The courtesy tailoring on a #kimono is the 'tomo eri' - the collar's friend. It's a piece half the length of the main collar which covers it and takes the wear and tear and can be removed or replaced. I add a little extra something - the fold of spare fabric hidden in the collar, that stiffens it, and also is there for repair. #sewing
