Robes
'Robes,' as in Revelation 7, signify truths of defense. Before they were washed they signified falsities. People in falsities from ignorance in the spiritual world appear first in obscure garments of various colors, and while they are in temptations, they appear in filthy garments. When they come out of temptations, they appear in 'white robes and clean' because of their purification from falsities.

The New Jerusalem and its Heavenly Teachings # 166
166. People believe that when our sins are forgiven they are washed away or rinsed off the way dirt is rinsed off with water. However, our sins are not washed away; they are just put aside. That is, we are held back from doing them when we are kept focused by the Lord on doing what is good; and when we are focused on doing good it seems as though our sins are gone and therefore as though they have been washed away. Further, the more we have been reformed, the more capable we are of focusing on doing what is good; how we are reformed will be explained in the treatment of regeneration that follows [§§173-186]. If we think that our sins are forgiven in any other way, we are sadly mistaken.
