Sorry, my post #11 to you. “Chicas de moda” means “stylish girls.” Maybe they are, and maybe they aren’t ... I haven’t seen their pictures!
As a personal thing, I’d expect a group called “Scholastic Voices” to be singing excerpts from the Unabridged Dictionary or the Summa Theologica. There’s a fantasy book where the people do this sort of thing for entertainment. It might be “Fairest,” by the author of “Ella Enchanted.”
Yes and what of the girl in a few years who gets an eating disorder because someone says she’s too fat to be in a group called las chicas de moda?
