So I was studying the start of Bame Isha in the Bavli (Shabas 57), and it seems a woman can't wear a tight strap or string in her hair outside (of an eruv) on Shabas (lest she remove it out of doors because she's going to be tovel). Looking at Shulchan Aruch (with Mishna B'rura) 303 seems only to confirm this (and apply it even to unmarried and elderly women). Yet it seems to me that very many a woman does wear a ponytail, bound by an elastic, outside of an eruv on Shabas. What gives?
- Am I misapplying the halacha to ponytail elastics? That is, does it not apply to them? Why not?
- Or am I mistaken about the prevalence of ponytail-elastic use on Shabas, and, in fact, those careful about halacha don't wear them?
- Or is it simply that many women sin — viz, wear ponytail elastics even though it's forbidden?
- Or what?
