If you want to be comfortable and safe while flying, don't wear these five things, according to Christopher Elliott of Tribune Media Services:
1. Heavy perfume or cologne
These scents may be your olfactory signature, but try to refrain before you board a plane. Perfume and cologne can permeate the interior of an aircraft, overwhelming and even sickening your fellow passengers.
2. High heels
Not only are high heels, especially stilettos, uncomfortable and restrictive on long flights, but also they can be a danger should you be forced to evacuate the aircraft using the inflatable emergency slides.
Ew! Find out the disgusting things people do on planes. Warning: This is crude and rude behavior.
3. Shorts
No matter how warm it is in your departure city or your destination, it's cold on planes--even in the summer. Wear shorts, and you're sure to regret it.
4. Light colors
Dark-colored clothes travel better for several reasons. If you spill something, the stain is less likely to be noticeable. You especially will appreciate this if your luggage is lost or delayed, forcing you to wear your travel clothes for a second day. Also, avoid synthetic fabrics because they can be hot and sticky. Instead, choose clothing made of natural fibers, such as cotton in the summer and wool in the winter.
5. Tight-fitting clothes
Pants, tops, dresses or skirts that are too form-fitting may be sexy attire, but they aren't the best travel attire. Not only are tight-fitting clothes uncomfortable on long flights, but also they can be dangerous by escalating deep vein thrombosis. Choose loose-fitting, non-binding clothes.
What should you wear on an airplane? Dress for success, especially if you're traveling internationally. Outfit yourself so you are comfortable, but also elegant. Look like you belong in first class, and you'll be treated like you do.
