Shelby and Brittany both forgot the cape (and dress!!!) at Shelby's apartment the morning of the wedding. Luckily, Shelby's sister saved the day and called them so they could turn around and grab them.
Brittany forgot her wedding boots (and the crystal crown) in the car and only realized two-thirds of the way into the hike to the peak. So, she wore her socks instead of her Hokas.
