During a MUN conference, one will be expected to dress in formal clothing. The dress code for MUN conferences is strictly formal. One will be expected to dress in suits (if male) or in equally formal clothing (if female).
The minimal requirement at a conference is to wear a pair of formal pants, a shirt, dark shoes and a blazer. However, it is preferred that male delegates dress in proper suits with a tie.
They are expected to respect that when wearing a skirt, the end of the skirt is no higher than five inches above the knees. When you keep your arms along your body, your finger tops should still be touching the skirt.
