Beyond the kippah that varies from optional to required depending on the sect one belongs to, certain sects have a strict dress code for both men and women.

But I'm fairly certain this person does not belong to any such sect, at least not based on the video thumbnails she has on her tiktok page. So I'm fairly certain she means this in the purely phenotypical sense, which to be honest with you is totally not 'visible.' Like, at all. Being a guy of southern euro-poor ethnicity, I myself have been clocked as jewish countless times which leads me to believe everyone just thinks anyone with a fucked up nose is jewish.
