The troubled British retailer AllSaints, which opened a New York flagship in Soho last May, began calling desperately for new investors this past March. They’re currently finalizing a deal with Goode Partners, an investor in Intermix and Bowlmor Lanes, and London-based Lion Capital, a key creditor to American Apparel. “We’re guardedly optimistic,” said an AllSaints spokesperson of the $166 million deal. Lion will buy 75 percent of the company, while Goode will take 15 percent, leaving AllSaints founder Kevin Stanford with a 10 percent stake.
