Easy way to mirror wardrobe (left to right)?

Exedore

I have a few wardrobe sets which have clothing specific to one side of the body.  For exmaple, White Knight has a gauntlet on the left hand, but a glove on the right.  Rocker has a wristband on the left arm only.  I want to use an item from the left arm on the right arm.  Changing X scale parameter to -100% accomplishes it for the base pose, but as soon as the figure is moved, it follows the left arm because the rigging is still on the left.  I found these instructions for the White Knight gauntlet, but it just seems way more involved and imprecise than it should be; it's essentially stripping out all the rigging and hoping Daz generates new rigging correctly.  Surely there's a better way?
