Chris Burch has been forced to step down as co-chair of the board of his former wife Tory Burch’s company. Chris was ordered out in a Feb. 22 boardroom showdown over the striking similarities between his new company, C. Wonder, and Tory’s eponymous fashion line and stores. A source told us, “Chris Burch is no longer co-chair of the board. Tory is the sole chair of the board, and this reflects how her company has been run since its inception. Chris never had an office or was involved in the day-to-day running of Tory Burch. While Chris remains a shareholder and a board member at Tory Burch, Barclays Capital remains engaged to sell his shares.” The source said Tory’s main concern was to avoid comparisons and confusion between their brands — and she has demanded Chris dramatically change his concept, even though he spent millions on his SoHo store and plans to open another at Columbus Circle in September. The source told us, “Tory is working with Chris to avoid more brand confusion. She is asking him to change his concept, which includes C. Wonder’s product, the design and the boutique. It remains Tory’s intent not to litigate — she is hopeful he’ll agree to change his concept. Litigation would be the very last resort.” The source added, “Tory has always said she wants Chris to be successful. He’s a great entrepreneur, but she wants him to do something unique and original, not to knock off her products.” A Tory Burch spokeswoman declined to comment. A C. Wonder rep didn’t get back to us.
