When I was a camper in a certain girls’ camp, I heard that the counselors have to wear the same outfit Shabbos day as they did Friday night. The reason for this was so that the campers should not feel the need to wear two outfits on Shabbos, even if their rich friends were. The point was to make it Shabbos, not a weekend fashion show. I thought this was such a nice and considerate rule.
Once I became a counselor, I realized that all the counselors wore two outfits (sometimes 3 – night, day, and a maxi dress for Shabbos afternoon), which either meant that the rule was slowly ignored until it slipped into oblivion, or that it never existed to begin with. Suffice is to say, I had to get some more Shabbos outfits when I went home for my day off 🙂
I generally like to wear two outfits on Shabbos, just for my own pleasure. It’s not meant to impress anyone that I own more than one outfit – on the contrary, I’m almost ashamed of myself when I see girls who do wear only one outfit throughout the whole Shabbos – I’m very impressed by this, because it reminds me of the rule (which may or may not have existed) that sought to alleviate the stress of fashion and fitting-in.
