Third anniversaries aren't typically imbued with the kind of gravity often attached to gold and silver milestones, but Hayden-Harnett's Toni Hacker and Ben Harnett, who started their line on April Fool's Day three years ago, are seriously happy to be designing right now. "I'm surprised we're still here!" a smiling Hacker admitted at last night's cocktail celebration at their Garment District showroom. Fans of the husband-and-wife team's handbags, accessories, and clothing are less surprised by the duo's relative longevity, and their Fall 2008 collection is already a big hit. Particularly swoon-worthy: their color-block totes, clutches, and shoulder bags. "It's totally a throwback to the eighties," Hacker explained. "You've got Memphis art school, super-saturated pastels, minimal hardware, and an emphasis on color." Harnett, who conceded that his wife was really "the creative genius" behind the line, is understandably proud of their collaboration. His favorite piece? The Laura black-and-metallic reversible tote. "It's a great combination of ideas and functionality," Harnett noted. "All in all, I think this is our strongest collection yet."
