What is now Destination XL Group was founded in 1976 by Calvin Margolis and Stanley Berger as Designs, Inc.

In May 2002, Designs, Inc. bought the Casual Male Big & Tall chain of stores out of bankruptcy and elected to focus their business on those stores, selling off their other businesses and assuming the Casual Male name.

In 2004, the company acquired Rochester Big & Tall Clothing, which gave the company access to a number of designer brands including Robert Graham, Tommy Bahama, Cutter & Buck, Jack Victor, and Robert Talbott. Also in 2004, Casual Male hired former champion boxer George Foreman to promote the chain and act as spokesman for new lines of clothing bearing his name.

In 2005, Casual Male changed the name of its stores from Casual Male Big & Tall to Casual Male XL.

In 2010, the company opened its first DXL store in Schaumburg, Illinois. Big & Tall customers were looking for a superior shopping experience – one that provided a better blend of quality, selection, and service. This new store opening marked the starting point of the company’s transition from Casual Male XL to DXL.

In May 2013, the company launched its first television and radio advertising campaign, entitled “No Man’s Land,” which supported the DXL brand.

As of 2016, there were more than 200 DXL retail stores in operation across every major metropolitan market in the United States.
