Clothing for a flight and what is practical
Short answer: On a plane the air is dry and the temperature varies. Layers you can take off, clothing that does not pull, and a pair of proper socks cover most of it.
Layers rather than one thick piece
It is cold by the window and warm in the middle. A layer you can take off is worth more than a thicker top. See sweat clothing.
Nothing that pulls
The body swells slightly on long flights. A wide waistband and loose legs are far more comfortable. See bamboo underwear for women.
Socks rather than bare feet
The cabin is cold at floor level. A stocking with even pressure can also help against swollen ankles. See bamboo support stockings.
Dry air
Cabin air is very dry. A material that takes up moisture from the air feels more comfortable than a synthetic one. See bamboo T-shirt for women.
Change on arrival
A clean set in your hand luggage makes the arrival noticeably better. See washing and care.
