How to put on a 14-strap suspender belt, a practical guide:
1. Set aside a lot of time
2. No more than that
Actual practical advice for belts with more than 6 straps: I find it works well to do the front most and rear most ones, then the “middle” one, and then the ones in between. Working your way from one extreme to the other results in badly spaced attachments (which will try to twist the stocking, which is uncomfortable)
