Make certain parts unaffected by sculpting brushes?

Hey guys, just registered here. I’ve been working on this outfit for a while, and I want to inflate the skirt but it’s behind the tails, so whenever I try to inflate it the tails also got inflated along with it since I can’t get the right camera angle to just sculpt the skirt without hitting on the tails.

The tails have their own material slot so I can easily select them, anyone knows if I can make it so they are temporarily unaffected by sculpting brushes? Thanks

What about selecting the tails by their material, and hiding them (H).
Then switch to Sculpting to do your inflating etc.
Then go back to Object mode and ALT-H to unhide the tails.
Does that work?
