Punk and the English underground are about as far away from the Hollywood Regency style of decor on which Kelly Wearstler made her name as you can get, but they were the starting point for her first pre-fall collection. The interiors-guru-slash-designer's 8- and 9-year-old sons are in a band called the Negotiators—"they were the youngest group to ever play the Whiskey," she said proudly—and she helped them get dressed for their performance, taking cues from old videos of the Clash, Thomas Dolby, and the Smiths on YouTube. That experience, in turn, informed this season's clothes. "There's so much inspiration there," she added.

It's a loose inspiration. Yes, she has shrunken leather motorcycle jackets and slouchy T-shirts and tanks, but the former aren't pierced with safety pins and the latter don't come with built-in holes. Specialized fabric treatments and prints, many of them handmade, are becoming Wearstler's calling cards, so the Perfecto looked like it had been dipped in white paint, oh, about a decade ago and the paint had slowly faded with use and age. The collection's strongest prints were a silkscreen-effect ink pattern (very cool on those silk cupro racer-back tanks and leggings) and a batik-ed black and white cube motif. Wearstler threw the trench over her own skinny acid-wash jeans and a faded concert tee; a model wore the elongated pencil skirt version with a faded and slightly oversize button-down called "the grunge shirt." Mr. Cobain might not approve, but Wearstler's confidence is paying off.
