Are down coats the new Botox?

This evening, some construction workers tried to strike up a conversation with me, or something like that, perhaps disproving John Derbyshire's theory that women cease to be attractive after age 20, making me a full two years past my prime. But of course Derbyshire referred specifically to how women look naked, and I was wearing a puffy winter coat; surely had I disrobed, these men would have lost interest entirely.
