soaked to the skin

Also, soaked through. Drenched, extremely wet, as in What a downpour; I'm soaked to the skin, or She fell in the stream and was soaked through. The implication in this idiom implies that water has penetrated one's clothing, so one is thoroughly wet. The phrase to the skin has been so used since about 1600; it and the variant were combined in Randle Cotgrave's Dictionary (1611) as “Wet through, or (as we say) to the skin.”
