That pic looks like a bunch of Jewish Amish brethren or some cocktail like that...
The ultra-Orthodox have a very strange but consistent look. Go to the right parts of Brooklyn and you'll see them (including some of my relatives) all over, looking just like that. Heck, drive down certain streets in Memphis on Saturday morning and you'll see them walking to synagogue. Don't know how they manage in the black suits in July.Another reason why dressing up for any type of religious service is a terrible thing and a practice that needs to go away entirely. I like the summer services where I go because it has a ton of cute girls and they're often wearing sex sundresses or miniskirts, very nice.
Of course now when it's cold that means a lot are wearing those cute hipster scarves, so it works out too.
Don't Orthodox Jewish services also have segregated genders like mosques? Ugh.
