Susan Rice was on PBS last week to discuss UN Security Council actions against Syria. She wore a beaded necklace and long, dangling earrings: http://youtu.be/VOMyLg_SL0k
You remember the last time we talked about long earrings, don't you? They can be endlessly distracting, as they are in this case. Part of the problem is that they are so long, they move even when she is barely moving her head at all. They also catch the studio lights, which draws even more attention to them.
The great thing about earrings is that they are easy and fast to put on or take off as needed. In that last minute check before going on camera, I would recommend taking these off.
