Anything that Lights Up
We've said this before and we'll say it again: You should rethink wearing any clothing that requires batteries or a power source. The blinking Christmas sweater -- or worse, sweatshirt -- might seem festive and whimsical when you catch it on a late-night TV shopping network. "Look! Rudolph's nose lights up! Adorable!" Really? It's a little too much for a work event. If you just can't live without your bling, try some sparkly jewelry or an elegant wrap with understated sequins or glittery thread instead.
