Son of a bee sting! Strange, I just re-inspected the whole thing and could not find any evidence of moth mastication. Could be there, I was pretty giddy when I found it in the women's section, especially since it is s perfect fit.
And not to worry, nothing other than the BB camel hair was found at that location (not even the Prada shoes actually).
Forgot to mention - picked up a pair of PRL charcoal flannels (flat front, coin pocket, button fly), marked 32x32 and available.
