The TSA (Transportation Security Administration) has issued the following suggestions for dressing to make your journey through airport security as easy as possible:

Be aware of what common items might set off the metal detector. Avoid wearing them, or hand them over to the security officer before you pass through the detector. These items include:

keys
loose change
cell phones
PDA’s
heavy jewelry
clothing with metal fasteners
hair barrettes
belt buckles
under-wire bras

Metal body piercings may set off the metal detector. You can ask to remove them in private rather than have a pat-down search.

Travelers must take off their shoes and put them through the x-ray machine separately. You then walk through the metal detector and reclaim your shoes on the other side.  It’s suggested that travelers wear slip-on shoes to make this process quick and easy.

You can wear loose-fitting clothing, but it may cause you to require additional screening. This may include a hand-wand or pat-down search.

Anyone can wear a head covering, whether religious in nature or not. It may cause you to be directed to additional screening, however.  If a pat-down search isn’t sufficient, the traveler will be asked to remove the head covering in a private screening area.

If travelers are required to undergo additional screening for any reason, they can always request a private screening area, and they will have a security officer of the same gender.

In short, a little common sense should help any traveler avoid delays in getting through airport security easily.  Just leave the suit of armor at home.  For more information, visit the TSA’s site.
