Charlie Chanaratsopon says he's in a race to capitalize on a burgeoning trend. Accessories are a $9.2-billion-a-year business in the U.S. and expanding swiftly. As a category, paired with beauty and footwear retailers, it grew six times as fast as other mall-based apparel stores from 2007 to 2012, reports Credit Suisse. "We've spent years brute-forcing things across the finish line," says Chanaratsopon.
