Groovy! Donald Fagen enrolled in Bard College in 1965, but he didn’t form Steely Dan with fellow classmate Walter Becker until 1970. For this costume, you will need hair, clothing, and an arsenal of era-appropriate phrases, such as “What is Steely Dan? That is just the name of a dildo from William S. Burroughs’ Naked Lunch to me.” Bonus: if you say these words in the mirror long enough, you might be able to convince yourself that you’re actually talking to another human being who is also dressed as Donald Fagen! Imagine how nice it would be to not be alone! Ha ha!
