Marc by Marc Jacobs Launches Full-On Denim Collection

'70s Flare Jean in San Francisco Wash, $228

>> For the first time, Marc by Marc Jacobs is dedicating itself to denim in a big way — instead of only producing denim pieces sent down the runway, the label is focusing on building a denim collection that stands on its own. For launch, there are nine new styles in 12 washes — including dark-wash trouser jeans; they start hitting stores this month and run $138-$228.
