This finally became available on the DMU portal:
How should I dress?
Dress for informational sessions is business casual. Of course, you are welcome to dress comfortably and casually for the evening social events. At DMU, business casual means looking relaxed yet neat and pulled together. Here are some examples:
For women: trousers, capris/long shorts that are tailored (no running shorts or short skirts). Jeans that are neat and in good condition are acceptable. No bare midriffs please!
For men: khaki trousers or shorts (no running shorts). Jeans that are neat and in good condition are acceptable. Collared shirt, sport shirt or t-shirt. Dress sandals or loafers.
