I work in an office, in IT, between non-Jews (and a handful of chiloni Israelis), in the UK.
For me, whenever I leave the neighborhood, I go ‘undercover’. Just a plain simple conservative shirt – white, blue or brown – and neat pants, a black/blue sweater and a winter coat (more like a sort of skiing coat), and a baseball cap over my kippah. Haven’t experienced much antisemitism here, really, but I just don’t want to stand out too much (and become a target for harassment or common crime). At work, I do go around with kippah all day.
Inside the neighborhood I dress ‘frum’…
I’m probably the only person wearing a shtreimel on shabbos who then wears a red-and-black skiing coat and baseball cap to work on Sunday morning (I work Israeli days, with Israeli customers). Oh well, I’ve always been unique…
