Some Panhellenic what-to-wear-for-recruitment pages are taking pains to say DON’T wear sequined or beaded dresses (sometimes just sequined are mentioned).
Is this a southern thing, or is it pretty general?
Are they trying to keep PNMs from showing up in things that may be too high school prom-y?
Has sad experience taught them that unless they say this, housekeeping staff will be complaining for weeks about finding stray sequins and beads in cushions, under furniture, and caught in the carpeting?
Some of it maybe to communicate that you should be dressing for day rather than evening wear because weirdly sometimes girls this age don't discriminate in outfits.
(I'll see stuff sometimes at the school where I work and wonder if they thought they were going to a night club.)
The other aspect I can think of is that even in later rounds, with the exception of prefs, you might sit either on the floor or on a metal folding chair. In either case, beads might be really uncomfortable and impractical.
The no-sparkles might be the same for the actives' side of it as well.
My D brought home 10 pages of instructions regarding her GLO's required outfits for their Panhel's recruitment. They have the parties in the evening once classes are done for the day but still are to avoid "beading, sparkles, sequins or anything that screams look at me."
