Jewellery or bulky accessories

Metal will slow you down at security – it’s one of the things more likely to get you flagged. Jewellery that can be hard to remove will also slow you down in the security line. Any jewellery shaped like a potential weapon also raises red flags and may be uncomfortable when you’re trying to lean back and get some shut-eye. Be careful with earrings too; they can easily fall off and get lost while you’re putting on or taking off headphones to watch a movie. “You don’t want to wear hoops that can get caught and pull on your ear lobe,” warns flight attendant, Amy Caris. Also avoid wearing your skyscraper heels on an aeroplane. The nails in high heels can trigger security metal detectors to go off, as can shoes that sport large metal adornments or studs.
Anything tight

Tight waistbands, skirts, blouses and shirts are all no-no’s while travelling, for the simple reason that our bodies naturally swell when we fly. Restrictive clothing does not pair well with bloating, also common on aeroplanes. You want to be able to move comfortably, encouraging healthy blood circulation and avoiding deep vein thrombosis. Avoid cramping by doing exercises in your seat and taking a walk to the lavatory, whenever possible.
An uncomfortable bra

One of the top items to avoid wearing while flying is an uncomfortable bra. A bra that digs into your shoulders and chest will only become more constraining in the air.
