Stop Wearing These on Your Next Flight, Warns Seasoned Flight Attendant – Her Shocking Reasons Make Perfect Sense

What you wear on a flight is something most people don’t think twice about.

But a seasoned flight attendant says some of the most common outfit choices can turn into a problem the moment you step on board — and once you’re in the air, you’re stuck with it – and in some cases, the effects don’t end when the flight does.

So what exactly made experienced cabin crew say, “Don’t ever wear this”? And should you really change the way you dress for your next flight?

Let’s look at what not to wear on a plane, according to someone who’s seen it all from 35,000 feet, because these are the type of travel tips we all need for better trips.

What This Flight Attendant Says You Should Never Wear on a Plane

Here’s what she recommends avoiding – and why:

1. Rompers or Jumpsuits

Cher’s take: “I will never wear a romper on a plane.”

If you’ve ever tried to navigate an airplane lavatory, you know the struggle – it’s cramped, turbulent, and the floors aren’t always dry or clean.

According to Cher, wearing a one-piece outfit like a romper means you’ll have to remove the entire garment just to use the bathroom, which puts your clothes at risk of touching the floor. And as she bluntly puts it, that’s “exactly where you don’t want your clothes landing” because those floors “are soaked with pee and it doesn’t get mopped often” and there is a significant amount of pee there.

2. Shorts

Cher’s take: “You are asking for ringworm or staph infection by wearing shorts.”

Shorts might seem comfortable (think of summer days!), but Cher warns they leave too much skin exposed to surfaces that aren’t as clean as they look.

She explains that passengers vomit, change diapers, and track all kinds of germs onto the seats and surrounding areas. Sitting in shorts puts your bare legs in direct contact with it all – and she doesn’t sugarcoat the risk of catching something from it. Shorts may feel like the obvious choice on a hot day – but according to Cher, they’re more of a health hazard than a convenience.

The Reality of Cabin Surface Hygiene

While aircraft use advanced filtration systems to keep cabin air clean, surfaces inside the plane are a different story. High-touch areas like seats, armrests, tray tables, and seatback pockets are not always thoroughly sanitized between flights.

This means that when your skin is directly exposed – for example, when wearing shorts – you may come into contact with residues left behind by previous passengers. Choosing clothing that covers your legs creates a simple physical barrier and reduces that exposure. 

3. Sandals or Open-Toed Shoes

Cher’s take: “The carpet on the plane floor is filthy dirty.”

According to her, the cabin floor is a high-traffic, low-sanitization zone where anything can – and often does – end up.

She mentions that passengers throw up, pets sit on the floor, and people rub their bare feet on the floor, all of which contribute to a space you really don’t want to walk on with exposed toes. Sandals might be your go-to in summer, but Cher makes it clear: they offer zero protection from the realities of the cabin environment.

4. Tank Tops and Tube Tops

Cher’s take: “You’re gonna freeze to death.”

Temperatures inside the cabin can drop quickly once you’re in the air. Without a jacket or outer layer, you may be left shivering – especially on domestic flights where blankets aren’t always provided. Cher has had passengers ask for blankets mid-flight – and she says there’s often none available to hand out.

Cher also says that when choosing your travel outfit, you should “err on the side of modesty”. 

Her Most Important Tip: Always Dress in Layers

Cher didn’t just focus on what not to wear – she also emphasized what you should do when dressing for a flight. And her top recommendation?

Dress in layers. “Never wear a sweater or a sweatshirt by itself without something under it.”

Cher’s warning: “We’ve had actual medical emergencies because somebody got overheated.”

That may sound surprising to some, but according to Cher, wearing a single thick layer – like a heavy sweatshirt – without anything underneath can backfire fast. Cabin temperatures fluctuate, and people who aren’t able to adjust quickly can overheat, especially during boarding or taxiing when airflow is limited.

Instead, she encourages flyers to wear multiple breathable layers, which allow you to adapt to the environment more easily. It’s a simple way to avoid both freezing and overheating mid-flight – and a piece of advice based on years of firsthand experience with in-air emergencies – one of those travel mistakes to avoid.

What Fabrics Are Safest to Wear on a Plane?

When choosing what to wear on a plane, most people focus on comfort, but fabric choice also plays a role in safety and overall comfort during the flight.

Many travel and safety experts recommend opting for natural fibers like cotton, wool, or linen. These materials are more breathable and less likely to retain heat, which helps regulate body temperature in a changing cabin environment.

By contrast, synthetic fabrics such as polyester or nylon can trap heat and feel uncomfortable during long flights. In rare situations involving high temperatures, these materials may also react differently than natural fibers.

For most travelers, the takeaway is simple: breathable, natural fabrics are usually the safest and most comfortable choice for air travel. 

What Is the Best Outfit to Wear on a Plane?

The best outfit for flying balances comfort, hygiene, and practicality. Most travel experts recommend:

• breathable fabrics like cotton
• layered clothing to adjust to temperature changes
• closed-toe shoes for protection and safety
• loose-fitting clothes that allow movement

Avoiding restrictive or overly revealing clothing can help prevent discomfort and make your journey smoother. 

More Advice From Other Flight Attendants

Cher’s video isn’t the first time cabin crew have weighed in on what to wear – or avoid – when flying. Over the past few years, several flight attendants have shared their personal dos and don’ts, often echoed in lifestyle magazines and travel segments.

Bonus Style and Safety Tips from Flight Crew and Frequent Flyers

Many seasoned flight attendants also recommend avoiding high heels when flying. In the event of turbulence or an emergency evacuation, they can slow you down or become hazardous on slippery floors.

Strong perfumes and colognes are best left at home. In a closed cabin with recycled air, even light scents can cause discomfort for nearby passengers.

While pajamas or ultra-revealing loungewear might feel cozy, they’re not the most respectful choice in a shared public space, especially when seated inches away from strangers.

Outfits that complicate the security process, like boots with multiple fasteners or layered belts and accessories, can create unnecessary delays at TSA checkpoints.

And when choosing fabrics, it’s smart to skip heavy polyester or synthetics. Breathable, natural materials like cotton or bamboo help regulate your body temperature when the cabin gets stuffy or unexpectedly cold.

Should You Change What You Wear on a Flight?

While there’s no universal dress code for commercial flights, airlines can – and sometimes do – deny boarding for clothing deemed inappropriate, offensive, or unsafe.

Cher’s viral TikTok doesn’t claim to be universal. She simply offers a behind-the-scenes perspective from someone who sees thousands of passengers a year – and a reminder that what you wear on a plane can impact more than just your Instagram selfie.

Whether you take her advice or not, knowing the reasons behind it is part of being an informed traveler.
