David Letterman's Wardrobe - On the late night show LATE NIGHT WITH DAVID LETTERMAN SHOW/NBC/1982-93, host David Letterman wore sneakers and blazers onto the program each night. His shoe size is approximately 10 and 1/2. A pair of his sneakers were once sold at a celebrity auction for $500. When his program moved to CBS in the fall season of 1993, David Letterman's casual attire of sports jacket and sneakers were dropped and replaced with a more conservative look of custom double breasted suits and polished leather shoes. Over the years Dave occasionally wore suits of a silly kind. They included attire made of Alka-Seltzer, Magnets, Marshmallows (they tried to light the marshmallows with propane torches but failed-the audience ate the marshmallows); Nachos (eaten by members of the audience after Dave was dunked in cheese), Rice Krispies (milk poured on Dave), Sponge (they weighed Dave, dunked him in water, then weighed him again, but it was off the scale). Suet (Dave went into a cage of birds), Vegemite, Vegetables, and a suit Velcro (Dave jumped onto a wall covered with the matching velcro grabbers and stuck).
