Initially it seemed fun and harmless. Those apple-cheeked boy bands practicing their cute choreography in silky, billowy ensembles that said “We’re romantic” or hip-hop-influenced uniforms that said “We’re tough, but not too tough for you, girl.” But the formula spread like mononucleosis to other groups.
