As a general rule, it’s best to dress in formalwear, or at the very least, business casual. Men, if you do not own a suit, wear a nice dress shirt and slacks. Women have a little more flexibility, but you can’t go wrong with a nice blouse, blazer and a long skirt (trousers are also acceptable). Accessories are fine too, in moderation. Neutral colors such as black, gray, brown and blue are suitable for both men and women.
