This is not an easy question.
You can add clothes to VaM figures, and you can remove clothes.
Some clothes are stiff, some have physics (they are moving and you can grab them).
There is an option at the clothes's physics tab (and the main clothes menue) that can enable so called "undress".
This feature will more or less disable the "anchor points" between clothes and the figure, so the gravity will pull it down. This will not work with stiff clothes and does not work equally well with different physics enabled clothing.
So don't be dissapointed.
You can grab physics enabled clothing with your VR hands, or mouse.
The "grab sphere" from this thread is for letting VaM figures grab clothes as well.
