Michael Kors Holdings, the designer’s namesake clothing firm, raised $944 million in an initial public offering, 19 percent more than it sought, after pricing its shares above the marketed range.

The firm sold 47.2 million shares for $20 apiece, according to data compiled by Bloomberg News. Kors Holdings had offered 41.7 million shares for $17 to $19 each on behalf of existing shareholders, according to a filing. The stock will start trading today under the symbol KORS.

Kors Holdings, whose sales surged more than 60 percent in the first half, plans to more than double stores over the “long term,” according to its prospectus. It also has opportunities to license the Kors brand, according to Steven Dennis, founder of the luxury consulting firm Sageberry Consulting.
