so, what did heian era women wear(with the 12 layered kimono)to tire their layers in place, since obis didn't really exist yet? would something like this work?^ (ik it looks like 6 but it was too hard for me to include 12 so pretend its twelve)
Hi again! You are pretty close to what junihitoe (Heian era "12 layered" robes) looked like yes :)
And don't be sad, junihitoe despite its name actually presented a wide array of robes number depending on wearer's eras and means ;)
Here is a video by renting shop Jidaiya showing how the collars are arranged once all the robes have been put on to obtain the desired kasane no irome effect:
And here is a pic showing the silhouette better:
You can find here a dressing tutorial explaining the order of the different layers:
