MELISSA CLOUTHIER is not happy about the male-cleavage fashion trend. “I have some news for Mr. Bastian: The ’70s were hideous. There were man perms. Remember the powder blue tux with ruffles? How about the wide lapels and the fat ties that fought them? This was the decade of Elvis Presley’s lamb-chop sideburns. And even now, ‘pornstaches’ (as in mustaches gracing ’70s-era porn stars) are scorned.”
