In 1948, Bing Crosby dominated over half of all the 800,000 hours of radio music played that year. Yet three years later, when the legend walked into a Canadian hotel, he was denied entry because he was dressed from head to toe in denim. After a few of what we imagine were the most mellifluous sounding DO-YOU-KNOW-WHO-I-AMs ever, Bing was let in. (Side note: people clearly saw him, and a serious trend was born.) Despite the lack of Internet, word of this encounter reached the Levi's headquarters in San Francisco, where work immediately began on the Bing Crosby Denim Tuxedo, now available again thanks to Levi's Vintage Clothing.
