Justin Thornton and Thea Bregazzi are feeling the festival vibe. "What someone wears to Coachella is as important as what they wear to an uptown event," opined Thornton. He and his wife had been discussing the Preen woman. She's grown up with the label, they decided, but hasn't lost her former edge—now she goes to the festival grounds from the boardroom.

Those two locations seemed more separate than that itinerary would suggest—at least judging by the clothes presented—but there were plenty of pretty, slightly retro pieces on display. The mix of mini florals, highlighter colors, and long, bias-cut shifts gave a nineties flavor—that decade, Thornton confirmed, is always a reference point. "It's the time we began, and the time that means so much to us," he said. A floor-length dévoré gown, speckled with flowers and cut on the bias, also made the case for "then for now."

Sportier bits, like gray marl hoodies, accessorized the debut of a new category for the label: swimwear. On the other end of the suiting spectrum, tailored separates had a sporty little detail, too: The tails zip off the jackets and—should you desire—on to the pants. Mix and match to go from the pool to the boardroom.
