Here’s something nobody tells you before a big trip: your outfit can turn a two-minute security walk into a fifteen-minute standoff with a stranger wearing blue gloves. TSA agents deal with thousands of travelers a day, and they have very strong opinions about what people show up wearing. Some of it makes total sense. Some of it will genuinely surprise you. And a few of these items get flagged so often that the TSA itself has started posting warnings about them online.
Let’s get into the clothing that drives security agents up the wall, plus a few facts about airport screening you probably never knew.
The Sparkly Sweater That The TSA Publicly Begged You To Stop Wearing
This one is real, and it came straight from the source. In December 2025, right in the middle of holiday travel season, the TSA posted on its official Facebook page: “TSA PSA: The body scanners don’t love sparkles. We don’t want to dull your holiday shine but we don’t recommend wearing your sparkly holiday sweater to the airport.”
That’s the government agency itself telling you to leave the sequins at home. According to reporting on the warning, the body scanners get confused by all those tiny reflective pieces, which means extra screening for you and a longer line for everyone behind you. One traveler on Reddit said they had to sit and wait ten minutes while an agent cleared a guy wearing a shirt with metallic threads. Another said a TSA agent patting them down flat out told them to never wear sparkles on a travel day.
Cargo Pants Are A TSA Agent’s Worst Nightmare
Former TSA agent Kimberly Pruitt spent more than five years at Los Angeles International Airport, and she put cargo pants and shorts at the very top of her list of problem clothing. Why? Those pockets. All of them.
“When being told by an officer to remove everything from your pockets, there is always a lighter or set of keys that you’ve forgotten in a hidden pocket,” she said in an interview about airport mistakes. Think about it. Cargo pants can have six, eight, even ten pockets. Most people can’t remember what’s in half of them. So the alarm goes off, you get pulled aside, and you’re patting yourself down like you lost your car in a parking lot. The fix is boring but effective: wear pants with fewer pockets and empty every single one before you get in line.
The Cartier Bracelet You Literally Can’t Take Off
This one is oddly specific and kind of hilarious. Pruitt named the Cartier Love bracelet as the single biggest jewelry headache at security. If you don’t know it, it’s a fancy metal bracelet that locks onto your wrist and can only be removed with a little screwdriver. People wear them for years without taking them off.
So when it sets off the metal detector, and it will, you can’t just slip it off and toss it in a bin. You’re stuck. That means a pat-down. Big metal necklaces and stacked bracelets cause the same problem. Interestingly, most wedding rings and quality gold or silver pieces sail right through, according to travel guides on jewelry. It’s the chunky costume stuff and magnetic metals that trip the sensors. If you’re a stack-it-all-on kind of person, the smart move is to put your jewelry on after you clear screening.
Too Many Bobby Pins Will Set Off The Alarm
File this under things that sound made up but aren’t. A head full of bobby pins can actually trigger the metal detector. So can elaborate updos, clip-in extensions, metal barrettes, and even wigs, which can prompt agents to inspect your hair.
Personal stylist Jennifer Koch summed it up perfectly when she told a reporter, “These scanners are unkind to fashionistas.” She’s not wrong. If you’re heading to a wedding straight from the airport and you’ve got twenty pins holding your hair in place, expect a second look. The advice from agents is simple: do the fancy hairstyle after you land, not before you fly.
The Hoodie That Started A Viral Fight
In early 2026, a woman posted a TikTok that blew up with nearly half a million views. A TSA agent told her she wasn’t “dressed appropriately” because she wore a comfy oversized hoodie to the airport. Her caption said it all: “IT’S WINTER IN THE MIDWEST. IT’S COLD.”
People were skeptical, but the TSA’s own rules backed the agent up. The real issue, as she later explained in the comments, wasn’t the hoodie itself. It was that she had nothing underneath it, so she couldn’t remove it for screening if asked. The TSA defines bulky clothing as “oversize pullover hoodies, large sweaters, cardigans, and ponchos,” and any of those can get you asked to take it off. The lesson from the whole hoodie saga is easy: wear a T-shirt under your hoodie so you can strip a layer without a problem. Hoodies aren’t banned. Just be ready to lose one.
Baggy Clothes Make Agents Think You’re Hiding Something
This is the big one that ties a lot of these together. TSA agents are trained to notice clothing that’s loose enough to hide something underneath. Droopy pants, flowy skirts, giant sweatshirts, and baggy dresses all fall into this bucket.
Koch put it bluntly: “Wearing bulky or especially oversized clothing, whether to be avant-garde or super comfortable, can look suspicious to TSA.” She even had her own run-in, wearing an Australian sweatshirt with a puffy kookaburra on it. The agent had a good laugh and told her to never wear it to the airport again. Volume, fur, and unusual materials all mess with the scanners. Maxi skirts and long dresses are especially tricky because agents may have to check that nothing’s hidden underneath. A common tip from seasoned travelers is to wear leggings or bike shorts under a skirt so you can quickly prove you’ve got nothing to hide.
Your Belt Is Coming Off No Matter What
Almost every belt has a metal buckle, and that metal buckle will set off the detector. Here’s the part that surprises people: even if your belt has no metal at all, an agent might still make you take it off. They don’t have time to inspect your belt and confirm the material, so off it goes.
One travel guide had my favorite line about this: if your pants fall down the second your belt comes off, don’t wear them to the airport. The easiest solution is to skip the belt entirely and wear pants that stay up on their own.
Why Everyone Takes Their Shoes Off
There’s an actual reason for the shoe ritual, and it goes back to a specific event. In 2001, a British man named Richard Reid tried to set off a bomb hidden in his shoe on a flight across the Atlantic. Five years later, shoe screening became official protocol for everyone.
That’s why agents beg you to wear slip-on shoes. Knee-high lace-up boots, complicated buckles, and shoes with a dozen straps grind the whole line to a halt while you sit there untying like it’s a shoelace competition. Pruitt said she personally wears sandals or anything she can slip off without using both hands. One more thing worth knowing: certain boots have metal shanks built into the sole, so they can trigger the detector even after you’ve emptied your pockets. And wear socks, unless you enjoy walking barefoot across an airport floor.
Offensive Shirts Can Get You Pulled Aside Or Kicked Off
TSA officers are trained in behavioral detection, which means they’re watching for anything that suggests trouble. A shirt with an aggressive or offensive message can put you on their radar and lead to extra questions.
Even if the TSA lets you through, the airline at the gate can still refuse to let you board. Spirit Airlines’ own rules ban passengers who are “inadequately clothed” or wearing anything “lewd, obscene, or offensive.” Back in 2022, model Olivia Culpo was asked to throw a hoodie over her sports bra before boarding. As one Reddit traveler put it in a thread about airport outfits: “If you wear a plain black hoodie and jeans no one cares.” The simpler your outfit, the smoother your whole trip.
The Takeaway
None of this stuff is technically banned. You can wear cargo pants, a sparkly sweater, and a Cartier bracelet to the airport if you really want to. But every one of those choices adds friction, and TSA agents notice. The travelers who breeze through are the ones in slip-on shoes, fitted layers, no belt, and minimal metal. Boring? Maybe. But there’s a reason experienced flyers all dress the same way. Save the statement outfit for after you land.
