Jack Henry, a traditional men’s clothing store, is closing after a going-out-of-business sale in Country Club Plaza in Kansas City, where the business has operated since 1931. “When the clothes are gone, the Jack Henry brand will be gone as well,” said Spiro Arvanitakis, a partner in the family-owned business. He called the closing “the end of an era for a Kansas City icon.” “The traditional needs of business clothing have more than evolved; they’ve dramatically changed,” he said. “Jack Henry doesn’t meet the current needs, which are more contemporary.” Jack Henry was founded by Jack Downing Henry, a native of Liberty. He studied merchandising at William Jewell College in the early 1920s before dropping out to work full time in a Liberty haberdashery.
