1. Brazil – Underwear Attire
While some of us don our most shimmery dresses for New Year’s Eve parties—or our comfiest pajamas to celebrate with a low-key night in—Brazilians take a much simpler, minimalistic approach to celebrating New Year’s: The dress code is for all-white attire, but the color of your underwear is thought to determine your arena of luck in the upcoming year. Want to find love? Pick the pink panties. Financial security may be attained by wearing yellow undergarments, and green is for good health.
