In the book there is a part where Odysseus makes it back to his homeland where he meets with the goddess Athene. She herself was disguised as a young shepherd to approach him and then reveals to him her true identity. She then disguises Odysseus to take back his home.
Athena tells Odysseus she will disguise him as a beggar, because she is the master of disguises and no one likes to look too closely at beggars anyway.
“Athena transforms him into an old man as a disguise. Clad in a filthy tunic, he goes off to find his faithful swineherd, as instructed by the goddess.”
