There's no particular style or type of clothing that you should wear from a security point of view. You are permitted to wear head coverings and religious garments during the screening process.You may be directed to additional screening if your clothing (religious or otherwise) is loose fitting or large enough to hide prohibited items. For more information, click here.
In addition, certain clothing and accessories can set off an alarm on the metal detector and slow you down. Avoid wearing clothing, jewelry or other accessories that contain metal when traveling through the security checkpoints:
1. Heavy jewelry (including pins, necklaces, bracelets, rings, watches, earrings, body piercings, cuff links, lanyards or bolo ties)
2. Clothing with metal buttons, snaps or studs
3. Metal hair barrettes or other hair decoration
4. Belt buckles
5. Under-wire bras
6. Hidden items such as body piercings may result in your being directed to additional screening for a pat-down inspection. If selected for additional screening, you may ask to remove your body piercing in private as an alternative to the pat-down search.
7. Take metal items such as keys, loose change, mobile phones, pagers, and personal data assistants (PDA's) out of your pockets.
8. Place heavy jewelry and other metal items in your carry-on baggage or in plastic bags if they are offered, until you clear security.
9. Pack all your coats and jackets in your baggage when possible. All coats and jackets must go through the X-ray machine for inspection. These include, but are not limited to, trench coats, heavy winter coats, suit jackets, sport coats and blazers. If you choose to wear an outer coat or jacket to the checkpoint, you will need to either place it in your carry-on or put it in the bin that is provided for you.
Disposable booties or slippers may be worn through the checkpoint to help protect your feet, but they must be disposed of prior to leaving the screening area.
Gel-filled bras are permitted through security screening and aboard aircraft.
Security Officers have to identify any metal that is detected at the checkpoint. If you set off the alarm, you will undergo additional screening. This includes a hand-wand and pat-down inspection.
You can remove metal items at the security checkpoint and place them in the plastic bags offered at several airports or in the bins provided. The bins will be sent through the X-ray machine. You can save time by not wearing metal items or by placing them in your carry-on baggage before getting in line.
