Though the language is symbolic, God foretold the humiliation of Babylon with vivid imagery (Isa. 47:1-3). Within this context, God is using very vivid imagery to speak about how He will bring Babylon to an open shame. 

1 “Come down and sit in the dust,

O virgin daughter of Babylon;

Sit on the ground without a throne,

O daughter of the Chaldeans!

For you shall no more be called

Tender and delicate.

2 Take the millstones and grind meal.

Remove your veil,

Take off the skirt,

Uncover the thigh,

Pass through the rivers.

3 Your nakedness shall be uncovered,

Yes, your shame will be seen;

I will take vengeance,

And I will not arbitrate with a man.”

~ Isaiah 47:1-3

Let us not negate the value of looking to such passages in our thinking (because the language is symbolic) upon the matter of nakedness, clothing, and modesty. The fact remains, that God is making emphatic points concerning the shame of Babylon’s sins, and how they will, indeed, be exposed. 

And about symbolism, can the tenderhearted truly remain unconvinced that certain imagery is meant to correlate with standards of propriety (See Ezek. 23:1-49; Prov. 7:10?)?

While such sins were trying to be covered, God says that when His judgment comes, they will be exposed. And they will be exposed in such a way that will bring shame to those people. After reading such passages, I certainly would not want to inch my way closer to revealing such things in a way that can bring about shame (Cf. Jer. 6:15).
