ASA dress code

I am a 4th year medical student and will be attending the ASA conference this weekend. I am planning on participating in the meet and greet with the program directors on Saturday in addition to other activities. Should I wear something business casual like khakis and a dress shirt, or should I wear a suit and tie to the conference? Thanks in advance.
