A few weeks ago, Canada-native Rebecca Zeidenberg joined the NEVERWORNS chat and wanted to wax poetic about her top Marc Jacobs finds. I suggested that a Neverworns piece might be the best way to share. I long covered collectors at Vogue, and these are the people from whom I’ve learned the most about clothes. (A Nicolas-era Balenciaga head. A couple who only wears Rick Owens.) A passionate collector is obsessed with even the most minute details of a piece of clothing and then uses those observations to tap into a brand’s history. Their whole world of clothes is informed by primary source grails and how the pieces look, feel, and even smell. Zeidenberg falls into this category.

Zeidenberg, who works in digital asset management at a medical technology company, first heard about Marc Jacobs when she was around nine while he was still creative director at Louis Vuitton. The first piece that caught her eye? A Murakami cherry print bag. “It did something to me,” she says.

Her Marc Jacobs obsession was reignited as an adult when she was finally able to access The RealReal in the United States after relocating from Canada to Kansas. (Hooray for domestic shipping!) She searched the resale platform using the classic “low to high” function and began matching her finds to the runway.

Her Marc Jacobs 18-piece collection is tight, edited, and chronicled in a spreadsheet that notes the date acquired, condition, color, provenance, purchase price, and details about celebrity and runway appearances. Her poison is Marc Jacobs of the mid-2000s and 2010s. In the mix is a groovy lime green paisley print Marc by Marc Jacobs jacket from spring/summer 2003. A powder pink bouclé Chanel-looking lady jacket from spring/summer 2004. Zeidenberg has managed to score the pieces for sinfully low prices: she nabbed a €50 leather bag1 with a hulking stone that was originally priced at $1,850.

Why is Marc so underpriced?
