I just came upon the following while reading a story:
"I put on the tightest pair of pants I could find, a pair that hugged my lower body like a second skin."
My reading mind left out the "a" in "like a second skin." But another part of my mind realized I had done that so I reread the sentence and analyzed it.
So what do you think? Is better with the "a" or without, #1 or #2?
1. "I put on the tightest pair of pants I could find, a pair that hugged my lower body like a second skin."
2. "I put on the tightest pair of pants I could find, a pair that hugged my lower body like second skin."
