I wasnt knocking your efforts just it required a level of technical understanding beyond mine. My default position when i have issues with clothing now is to hit reset and fix layers until everything goes away and I can start again
So looking at the video (thank you to Wulfie) as well as your guide, a beginners guide for complete idiots like me would appear to be
1. You cant use BOM on your existing mesh body even though you now have a BOM compatible viewer
2. See if your body has been updated to be BOM compatible.if not and you don't want to do anything technical wait until it is
3 Once you have a compatible body you should be able to wear your old clothing on the updated body simply using add to wear.
4. If that doesn't work its probably something to do with your skin that is stopping it, and you will need to ask your body/skin creator/ help group for assistance if you cant sort it out yourslf
