Amazing quality. Construction is fantastic and this is in beautiful condition. There is some fading to the interior lining. No moth damage. Stunning suit. I believe that it is tweed but I am not a fabric expert. Please see photos for all measurements. Hand tailored. This suit has two pockets and the fabric is heavy and thick.

A bit of information about the 28 shop.

Marshall Field's 28 Shop

Marshall Field and Company was one of Chicago's oldest and finest department stores.  In 1941, the store opened it's exclusive 28 Shop which was one of the first in-store boutique shops in the U.S.  The 28 Shop was the brainchild of Hughston M. McBain, who would go on to become manager of the entire company in 1943.  The 28 Shop was named for it's private elevator entrance at 28 East Washington St. and featured 28 dressing rooms.  It was here that Marshall Field's sold high end clothing from many of America's best designers.  After the war, fashions from Paris were also featured.

The 28 Shop was designed by Joseph Platt who arranged those 28 dressing rooms around a central salon.  There were 2 each of 14 different dressing room designs, all in various colors and decor to suit the customer's taste.
