For Marc Jacobs's diffusion line 'Marc by Marc Jacobs', the designer went for the rock looks of yesteryear for next spring, offering up a blur of pastels, sequins, stars and radiowave stripes. From the bright blue on models’ eyelids to the lightning-jagged patterns on dresses and giant star motifs, the electrifying look for the label was unveiled in a large, brightly-lit industrial building alongside the Hudson River.

Models walked to the energizing sound of Jeffrey Lewis’ “WWPRD (What Would Pussy Riot Do)” — an ode to the female activist Russian punk rock group. Two members have been jailed over a church protest.

Shiny satin varsity jackets and dresses had a 1950s feel while a jumpsuit made entirely out of sequins was a throwback to the 1980s. Pants were slouchy, and several shiny dresses had large stars in silver or black snaking up the side.

Female models had scarves tied tightly around their hair and necks, while some wore guitar pick necklaces.

It was the first of two outings for Jacobs this week — he shows his main line on Thursday, the last day of New York’s fashion parade.
