Aside from certain modesty laws that govern a persons behavious even in private, there are certain laws that govern the activity of Jewish women in the presence of men (like singing, or dressing in a modest manner). Must women observe those laws of modesty in front of gentile men?
- Singing in front of a non-Jew,
- Exposure (swimsuit, immodest clothing)
- Public displays of intimacy/affection
Sources would be appreciated.
