While most people obsess over what's visible on New Year's Eve (the sparkly dress, the perfect suit, the midnight-kiss tiara), the real magic might be happening underneath. From Italian nonnas gifting crimson briefs to Chinese zodiac believers wearing red for an entire year, underwear superstitions span continents and cultures with the kind of fervor usually reserved for sports teams and family group chats.
Here's your complete guide to lucky underwear: what each color means, where the traditions come from, how athletes take it way too far, and how to build a ritual of your own.
The Psychology Behind Lucky Underwear
Before you roll your eyes at Aunt Maria's insistence that you wear red on New Year's Eve, consider this: there's real psychology behind why people swear by their lucky drawers. Researchers use the term enclothed cognition to describe how the clothes we wear, and the meaning we attach to them, can shape the way we think and act.
Belief in luck can matter too. In a well-known 2010 study, participants who were told they had a lucky charm reported more confidence and, in some tasks, performed better. Later attempts to replicate those results have been mixed, so think of lucky underwear as a confidence tool rather than a guarantee. But confidence is not nothing.
Underwear has a special advantage here: it's the closest thing to your skin. A rabbit's foot dangles from your keychain and a lucky penny sits forgotten in your wallet, but your underwear is right there with you all day, a constant, private reminder of the intention you set when you put it on.
Color-Coded Luck: What Each Underwear Color Means
If you thought choosing underwear was just about avoiding visible lines, think again. Cultures around the world have developed color-coding systems that would make a feng shui master weep with joy.
Red: The Universal Champion of Love and Luck
Red is the Beyoncé of lucky undergarments: universally beloved and guaranteed to make a statement. In Italy, wearing red underwear on New Year's Eve is practically law, and families gift biancheria intima rossa to bring the recipient love and prosperity in the year ahead. Spain follows the same custom, and in China red is considered so powerful that some gamblers wear red underwear to the casino for an extra edge.
China also takes red to marathon levels during your ben ming nian, your zodiac birth year, which comes around every 12 years. Tradition says you wear red every day of that year to ward off bad luck. That's 365 days of commitment to your unmentionables. Get started with our red underwear collection.
Yellow and Gold: Money, Honey
Want to attract wealth? Skip the lottery tickets. In Brazil's Réveillon celebrations and across much of Latin America, yellow underwear on New Year's Eve symbolizes prosperity and financial success, and Filipino traditions embrace golden hues for abundance too. It's sympathetic magic at its finest: wear the color of money to attract money. Read more about why yellow underwear brings good luck on New Year's.
White: Peace, Purity, and Fresh Starts
On Brazil's beaches, millions of people ring in the new year dressed head to toe in white, underwear included, often in honor of Iemanjá, goddess of the sea. White stands for peace, spiritual cleansing, and new beginnings. It's a reset button for your luck, assuming you can keep white underwear white for more than five minutes.
Green: Health, Growth, and Good Vibes
Green underwear symbolizes health, renewal, and personal growth. It's the color of nature, of money in some countries, and of that feeling you get when you finally remember to water your plants and they don't die.
New Year's Eve: The Global Lucky Underwear Holiday
December 31st is the Super Bowl of underwear superstitions. The rules vary by country, but the core belief is the same: what you're wearing under your clothes at midnight sets the tone for your whole year.
- It should be a gift. In Italy and elsewhere, lucky underwear is supposed to be given to you by someone else. Apparently buying your own is like trying to tickle yourself.
- It should be new. Many traditions hold that a fresh pair carries more luck than one that's already seen a few laundry cycles.
- Timing matters. Some people wear their underwear inside out until midnight, then flip it right-side out to "turn" their luck. Others toss the pair after the night is over to mark a clean break. (Consider donating instead.)
- Stack your rituals. In Spain, red underwear pairs with eating twelve grapes at midnight, one for each chime. In Turkey, red underwear fills market stalls every December. Why settle for one superstition when you can hedge your bets?
A Global Tour of Lucky Underwear Traditions
Europe: Where Underwear Gifts Are Serious Business
Europeans have turned lucky underwear into both an art form and a retail event. Italian shops see red underwear sales spike every December, and families treat the annual underwear exchange as seriously as Christmas presents. In Spain, the selection of the right pair is part of the elaborate midnight celebration.
Asia: Zodiac Years and Serious Commitment
Chinese tradition ties red underwear to the zodiac and Lunar New Year. During your ben ming nian, a red pair isn't a one-night stand; it's a year-long relationship, and some people stock up on dozens of pairs to make sure they never run out of luck-inducing coverage. In the Philippines, New Year's celebrations lean on round shapes and gold tones to invite prosperity.
The Americas: From Beaches to Baseball
Brazil's New Year's Eve is the most spectacular of all. Revelers in white jump over seven waves at midnight, making a wish with each one, while underwear colors signal the kind of luck they're after. Across Mexico and much of Latin America, a multicolor system applies: red for love, yellow for money, green for health, white for peace. And in the US, sports culture has built an entire ecosystem of underwear superstitions of its own (more on that below).
Beyond Color: Fabric, Pattern, and Style Superstitions
Color is just the beginning. In the Philippines, polka dots are a New Year's favorite because the circles are said to represent coins. Some people believe a new pair holds more power than a well-worn one, and others swear certain fabrics carry better luck than others.
Then there's the inside-out move, which shows up in several cultures based on the idea that reversing your underwear can reverse your luck. It's a wardrobe-based Uno reverse card: slightly less comfortable and a lot harder to explain if anyone notices.
Sports and Lucky Underwear: When Athletes Get Superstitious
Professional athletes have elevated lucky underwear from cultural tradition to performance art. The most famous case is baseball's Jason Giambi, who kept a gold lamé thong in his locker to break hitting slumps and lent it to teammates. Derek Jeter later admitted he borrowed it during an 0-for-32 skid in 2004, and hit a home run the first time he wore it. Coincidence? Ballplayers think not.
Then there's the "don't wash it during a winning streak" rule, which turns some locker rooms into biohazard zones. It's dedication to superstition that borders on biological warfare.
Superstitions like these are common in sports: surveys of athletes suggest more than half keep at least one, with pre-game rituals, lucky charms, and lucky clothing topping the list. Whatever the mechanism, the confidence and focus that come with a familiar ritual are a real part of the mental game.
Lucky Underwear in the Social Media Era
Instagram and TikTok have turned underwear superstitions into seasonal content. Every December, creators share their New Year's Eve color picks and explain the traditions behind them, which spreads customs from one culture to people all over the world. Ancient beliefs, meet modern oversharing.
Retailers have noticed too. Red underwear becomes a seasonal bestseller wherever these traditions run deep. At Shinesty, we appreciate the business, but we're more focused on making underwear so comfortable you'll feel lucky in any color.

Does Lucky Underwear Actually Work?
Skeptics will point out that there's no magical force emanating from your briefs, and technically they're right. But if wearing red makes you feel more attractive, confident, or optimistic, those feelings can show up in how you act: you might take the shot, speak up in the meeting, or walk into the room like you own it.
Underwear superstitions also do something bigger. They connect us to our families and heritage, give us a sense of control when the future feels uncertain, and create shared rituals with millions of people doing the exact same thing at the exact same moment. Whether you're honoring an Italian nonna, a Chinese zodiac year, or a Brazilian beach tradition, you're part of a global community that believes a little magic starts with what's closest to your skin.
