Q. Does YCCC have a dress code?

The easy answer to this question is no.  YCCC does not have a dress code.  But if you have a more complex question, such as "how should I dress when teaching?", my recommendation is to consult google to find a few different and humorous answers from a variety of instructors who have asked this question at other institutions.  This blog post has a more serious answer with links to other articles on the topic.
