Do kibbutzim have a dress or behavioral code that they expect ulpanists to adhere to?
Much has been written about how a kibbutz is a social experiment or an economic unit. What tends to be forgotten is that a kibbutz is first and foremost the home of the people living there, the kibbutzniks. Therefore, it is expected that ulpanists will behave and dress in an appropriate manner. You definitely should not have any hesitation about asking your kibbutz supervisor if you have any questions about what is acceptable or unacceptable dress and/or behavior on your kibbutz. Better to ask first than be embarrassed later.
