What Not to Wear on an Airplane

When it comes to air travel, comfort and practicality are the real first-class tickets. Whether you’re heading on a long-haul flight or a short domestic hop, what you wear on the plane can make all the difference between arriving refreshed or feeling rumpled and restless.

While most of us plan what to pack, far fewer think about what not to wear in the sky, and there are plenty of clothing choices best left behind at the gate. That pair of skinny jeans might look great, but it’s one of the worst things to wear on a flight.

Sitting for hours in tight clothing can restrict circulation, increase discomfort, and even raise the risk of deep vein thrombosis (DVT) on long-haul journeys. The best option is breathable, stretchy fabrics that allow movement, think soft joggers, relaxed trousers, or loose dresses. Your body will thank you somewhere over the Pacific.

High Heels and Hard-to-Remove Shoes

Airports already involve a fair bit of walking, and airplane cabins aren’t exactly known for spacious aisles. High heels or shoes with stiff soles can make the trek from gate to gate uncomfortable, and they’re impractical if you need to move quickly during boarding or disembarkation. Security checkpoints can also make elaborate footwear a hassle. Opt instead for supportive sneakers or slip-on shoes that make security a breeze and keep your feet happy during flight.

Avoid Heavy Fragrances

Airplanes are enclosed spaces where hundreds of people share the same recycled air. What smells pleasant to one passenger might be overwhelming—or even trigger allergies—for another. Heavy perfumes, colognes, or scented lotions can quickly fill the cabin, creating discomfort for those nearby. The golden rule of in-flight etiquette: go scent-free or stick to light, neutral products. Your fellow passengers (and the flight attendants) will silently thank you.

Say No to Shorts and Revealing Outfits

While the cabin may seem warm when boarding, temperatures often drop mid-flight. Shorts, crop tops, and other skin-baring outfits can leave you shivering once the air conditioning kicks in. Airplane seats and armrests can also harbor bacteria from previous flights, making bare skin less than ideal. Instead, choose layers, comfortable trousers, a soft T-shirt, and a cardigan or hoodie that can be adjusted as needed. Layers are not only practical for temperature changes but also make long-haul comfort much easier to manage.

Fabrics That Don’t Breathe

Synthetic materials like nylon or polyester might look sleek, but can trap heat and moisture, leaving you sticky and uncomfortable during long flights. Cotton, bamboo, or moisture-wicking fabrics are far better options. They allow air circulation, prevent irritation, and help regulate your temperature when you’re sitting in the same position for hours.

Avoid Excess Accessories

That statement belt, chunky necklace, or stack of bangles might complete your outfit, but it can cause headaches at security and discomfort in the cabin. Metal accessories often trigger alarms during screening, and anything bulky can dig into your skin or make resting awkward. Keep it simple and opt for minimal jewelry and accessories that won’t interfere with your comfort or the scanning process.

Rethink Open-Toed Shoes

It’s tempting to slip into sandals before a beach holiday, but open-toed shoes on planes are rarely a good idea. Cabin floors can be unclean, and if an accident or spill occurs, your feet are completely exposed. Closed-toe shoes offer better protection and warmth, especially during long flights or unexpected delays.

Dress for the Destination

It’s fine to dress for where you’re headed, but balance style with practicality. A long flight is not the time for stiff fabrics, overdressing, or risky footwear. When you land, you can always freshen up or change into something more stylish before heading out to explore.

The rule of thumb? Dress like you’re ready to relax, not rush the runway. A comfortable traveler is a happy traveler, and the right outfit can make your journey smoother from takeoff to touchdown!
