You can be as prepared as you want, but things still go wrong. Try to get ahead of this by premaking or buying an on-the-go bag with backup necessities.
"Pack a cosmetic bag that has anything you'll need to touch up and refresh during the rehearsal dinner or at night to prep for the big day," instructs Law. "Include eye drops, tissues, pressed powder, lipstick, mints, deodorant, and a band-aid in case your shoes are rubbing you the wrong way."
You can also ask one of your bridesmaids or maid of honor to help out. "I suggest the bride designate a bridesmaid to bring extra bobby pins, curling iron, hair spray, texturizing spray, or anything for that matter, just in case a bride forgets!" says Bradford. "Two minds are better than one, and any extra hair tools or products keep you safe, rather than sorry."
