hi im having a similar problem.

Im using the stanard V3 SAE model from daz. i load on utilize V3 which i see the fixer there is wearing the helmet i think. i conform the clothing , looks good but when i animate the clothing bleeds through.

Whats the best solution. Try convert it to dynamic clothing?
Use magnets?
Use body morphs and key them to make the clothing look right?

Thanks
