Pack your bags! Late October Charleston weather is typically characterized as mild and  pleasant autumn weather. You will want to include lighter materials, but also incorporate layers as the weather can sometimes be unpredictable. Evening events are smart casual, pants, skirt, or dress for the ladies and pants and button down shirt for the men are appropriate for both nights. Charleston is a walking city, so comfy shoes are a must. Don't forget appropriate attire for your preferred activity along with sun protection; Charleston can still have plenty of sunny days in the fall.
