There isn't a lot of room on an airplane, so you shouldn't bring anything that will make you feel even more crowded. This is not the time to wear your jeans too tight.
When deciding what to wear on a plane, look for stylish tops made of natural fibers that let air through, like cotton, silk, wool, or linen.
Sitting for a long time could cut off blood flow and make your legs bigger. Deep-vein thrombosis and leg and foot pain can be avoided with compression socks.
To look your best & feel most at ease throughout your flight, layer your clothing. You can never tell if you'll get hot or cold during a flight, so bringing a light cardigan is a safe bet.
You do not have to change from dresses to slacks just because you are flying. The best will keep you safe and comfortable.
Flight attendants agree that flats are the best shoes to wear on a plane, but if you must wear heels, block heels are the most stable.
A cashmere or wool shawl elevates your look while also serving as a blanket, pillow, or extra layer on the plane without taking up too much room in your carry-on.
Wear something soft and loose that you wouldn't mind lounging in. You can dress in modal cotton sweats or harem pants.
A pair of lightweight, foldable slippers—ideally with a rubber sole—would suffice and be of great use in the hotel room.
