"Always True to You in My Fashion" is a 1948 show tune by Cole Porter, written for the musical Kiss Me, Kate. It is based on Non Sum Qualis Eram Bonae sub Regno Cynarae, a similarly ironic poem by the English Decadent poet Ernest Dowson (1867–1900), which has the refrain 'I have been faithful to thee, Cynara, in my fashion,' and which was probably inspired by Dowson's lifelong friend Adelaide Foltinowicz, who never returned his devotion. The phrase "faithful in my fashion" entered the language before the song was written, and was the title of a 1946 Hollywood movie.
