We awarded the Boulder Common Threads the Best Boulder DIY Boutique of 2009 on the laurels of its unique combination of secondhand chic boutique and community-conscious sewing studio, and then called it the "boutique of the future." But although Denver's new annex, on South Pearl Street, is much smaller and comes with only the boutique element intact, it still follows that prediction, seamlessly hanging both chic new clothing and upscale secondhand from its racks, with a dollop of recycled-green pride. Other differences? The Denver store is curated with a more citified working-girl clientele in mind than in Boulder, featuring still-chic, better-brand consignment items on its carefully ministered racks. We dare you to come in and not leave with some little treasure tucked under your arm.
