stuffed cabbage-u sound like a brooklyner…do u by any chance live there???
i’ll assume its a yes…
well, outside of brooklyn theres a place called “out of town” and while “out of town” keeps ALL the HALACHOS of tznius, things like tightness, type of socks, and color are diff in every community…
in brooklyn anklets arent so much accepted, neither is bright colors, and neither is tight clothing, but…
in other communities it is accepted and thats the norm, thats the tznius of their community…
ex: bright yellow shoes are not “tznius” in brooklyn, but if you would go to bais yaakov miami, plenty of girls are wearng them and its ok…
since sternberg has majority of their campers from “out of town” everyone is asked to dress in a way that is appropriate for THEIR community…
so to answer ur question they are being tznius after all…
however if they would go against halacha, tht would be looked down on…
