I redid the weighting from scratch again, with fitmesh this time. Good results, when Avastar doesn’t completely glitches out…

The bottom edge is surprisingly … wide compared to my hips so I must have done something wrong there. Additionally I noticed a few odd gaps that are probably due to some bad edge splits.

The texture for the back straps is the wrong one because I’m lazy. I also added a few extra edge loops to the front loop, it looks a bit less jagged now. The fitmesh stuff doesn’t quite work on the chest yet either, that’s another thing I need to work on. Don’t expect full breast size range tho, I did some testing and it simply looked terrible.
