We propose the concept of perfect vectorial vortex beams (VVBs), which not merely have intensity profile independent polarization order and topological charge spiral phase, but also stable state (SoP) upon propagation. Utilizing a Sagnac interferometer, we approximately generate VVBs with locally linear elliptical polarizations, demonstrate that such can keep their SoP at certain propagation distance.
