A garment of the entwinings of gold and of needlework, as in Psalm 45:13, signifies the Lord's divine truth.

A garment down to the foot, as in Revelation 1:13, signifies the leading divine which is divine truth.

It is said, in Deuteronomy 22:11, "Thou shalt not wear a garment of diverse sorts; as of woolen and linen together…”. This means that the states of good and truth should not be mixed up: people in the spiritual kingdom of the Lord cannot be also in His celestial kingdom at the same time, and vice versa.
