Yeah, it's not really challenging or time-consuming to wear a kimono if you're carefree about the neatness...
You only need one belt for every item of wafuku. So if you see a vintage kimono for cheap and don't want it to be abandoned, you can make use of it with one cloth belt and then a suitably encompassing set of inner clothing (as undeerwear to protect the kimono from body sweat). Or if you have a nagajyuban then it's one more belt for that.
Once you have the kimono, you can just set up the skirt and do a hip tie and you're done. The skirt is rigid and you can let the top just be loose, as though you're a samurai. Or use a clip to clip the two halves together as a collar.
Wearing guides tell you to aim your skirt in a careful way, that is under the assumption you don't have a mirror to notice the two halves of your skirt are misaligned. If you have a mirror just look at it and adjust as needed.
