In July 2007 Wearstler opened a boutique in Bergdorf Goodman's home-furnishings department, and the following year her office was based in West Hollywood on La Cienega Boulevard. Also in 2008 she introduced a line of decorative home goods for Bergdorf Goodman, which was sold out of her own retail shop in the store. In late 2008 she started working on a line of jewelry, scarves, bags, and belts, with plans to expand into women's apparel at a later time. By 2009 she had designed the top suite of the Las Vegas Hard Rock Hotel and a home for Stacey Snider of DreamWorks, and was in the process of decorating a large contemporary house for Gwen Stefani and Gavin Rossdale. She released her book "Hue" in early 2010, which features photography in chapters organized by color. Wrote the "Los Angeles Times" about the book, "Hollywood glamour, neoclassical ornamentation, pattern and texture prove to be Wearstler signatures, but color, she writes, 'is everything.'" In 2011 she was named to "Architectural Digest's" AD100 list, which is also dubbed the Top 100 Architecture & Interior Design list. The French version of the publication would also name her to its World's Top Interior Designers list.
