The council will vote on new decorum rules in September, seven months after a resident stepped up to a microphone in his boxers.
The rules were already under review, but that incident led to a proposed ban on undressing during meetings.
It's not the first time the university town has wrestled with how much clothing is enough.
In April, the city barred teens and adults from showing their genitals in public. That could put the wraps on two annual traditions that involve running or cycling naked.
But the council declined to outlaw topless females, despite complaints about a woman who gardens in a thong and gloves.
