Most couples choose to change into their main wedding clothes towards the top of the trail so they don't get their wedding attire sweaty and dirty or have to fight to move, but you can also throw a backpack over your dress/ suit if you don't mind a bit of red rock ombre along the bottom and choose clothes that have enough give for big movements.  The main thing is to wear shoes or hiking boots with good grip and stability.  The climb can be slippery and you don't want to get injured going up or down. General Pack list: Hiking boots/ good gripping soled shoes Backpack to keep your hands free while carrying any gear Wedding Attire Any details- rings, bouquet, vow books, etc… Touch up makeup and hair items WATER!  At least 1 liter for each person. Snacks- electrolytes, energy bars, dried fruit, etc… Sunscreen- The desert sun is harsh, be sure to protect yourself with a strong sunscreen, sunglasses, ang possibly a hat depending on the day Loose flowy clothing or moisture wicking fabrics  Pants with plenty of stretch to take large steps Hiking poles (optional, but very useful coming down the slick rock) A great attitude- this hike is no joke!!!
