Shopping 613: kudos to your school for enacting such a smart rule. No relevance to in or out-of-town. Just lowering the stress level for those that don’t have 5 “perfect” outfits for each seudah etc. and minimizing the heavy garment bag schlep.
Goq: these are for the most part non working teenage girls from families with multiple children whose tastes in clothing far surpasses their parents’ budgets. Even with closets full of clothes, the panicked mantra for many before such an event is “Mom, I’ve got nothing to wear for this Shabbos, and I need AT LEAST 4 OUTFITS! Can we still manage to squeeze in some shopping, or maybe it’s better if I stay home?”
So please cut the school some slack. They’re doing the right thing, and the one outfit can be pretty. No one said it needs to be one-dimensional, whatever that is.
