Lots of Jewelry

While a little sparkle quickly jazzes up any outfit, it isn't always the easiest thing to take off (think too-tight rings and tiny clasps). If you still want to bring jewelry to wear once you arrive at your destination, keep it in a separate bag inside your carry-on so that it's easily accessible for security. If you have particularly valuable items, request a private screening, says Glassman, to avoid becoming a target for pickpockets. And while studded pieces are certainly stylish, the TSA doesn't necessarily embrace this edgy fashion trend. Save the spikes for occasions that don't involve a metal detector.
