I understand what both of you are saying... but there is one way to do unrigged clothing without that much hassle.
If you take a look at cold breath cargo [ https://marketplace.secondlife.com/p/Cold-Breath-Cargo-Pants/5460770? ] they have both an unrigged and rigged versions.
The unrigged version comes in pieces [hips/pelivic area, Upper Legs, Lower Legs] that you attach as seperate parts on the legs and resize/shape how you need. It does work and allows for non-t-pose..SO you do need a bit of basic modding experience but it is very do-able.
So by creating this thread I was hoping someone would know of some mesh clothes that would have a simular set up to that?
