I don't recommend using it with any skeleton that edits body scales such as XPMS or Subtle Male Skeleton. Technically nothing bad happens but the armor is already modeled to be rather thin and those skeletons will slim your waist to scary proportions. TL;DR don't blame me if you look like a wasp.
To avoid misunderstanding: It is NOT incompatible with XPMS. The armor just will not have the intended shape on male characters. If this doesn't bother you, or if you play female character, don't mind it.
