I have Karliner relatives in EY (who I’ve been to several times and whose friends and neighbors, particularly the women, I’ve often for various reasons met). This is what I’ve observed.
Women dress ordinary charedi, not necessarily with a double covering and suchlike. I’m not sure if women drive. Men do not necessarily wear streimlach. Girls learn normal Bais Yaakov Chumash. Not sure about boys, but girls learn secular studies including English starting sixth grade. I don’t know if this is unique, but a lot of the ones I’ve met (though I could have an availability bias) have been either baalei teshuva or newcomers to chassidim and are often drawn by the intense feeling and spirituality. They seem very down to earth, substance over style.
