What to Never Wear on a Plane, From a Flight Attendant

Tight clothes

Avoid tight clothes, especially when your flight is longer than 4 hours. People on a long-distance flight are at a risk of DVT (deep vein thrombosis). DVT is a blood clot that forms in a deep vein, usually in the leg. To prevent it, wear special compression socks and loose comfortable clothes, and walk around whenever you can.
