Leonard Adler & Company

Established in 1903 to provide sewing supplies to the garment industry, you could say Leonard Adler & Co knows its stuff. Today, the old-school warehouse location still takes pride in being Chicago's go-to for all garment construction supplies (thousands of buttons, zippers, retail supplies, threads, and more–to give you a taste). It also has a small fabric selection, comprised of primarily menswear. The store serves as the provider of choice for several local design programs, schools, and universities (so you know it's the real deal).
