Don't add glitter. Glitter and sparkle on the eyes (or anywhere on your body) is more about "party" than "office." Save it for your New Year's Eve soiree.
Do wear a brighter lipstick. Even a subtle change in your lipstick shade can dress up your look significantly. Treat yourself to a slightly brighter shade, or enliven the shade you normally use by adding a layer of another more vivid tone. If you normally wear plum, for example, try adding a layer of crimson on for a slight gleam.
Don't wear lip gloss. Matte lipsticks will last longer and are better suited to eating and drinking on your feet. Gloss will end up on your glass. Also, shiny lips may seem a little too sexy in some corporate headquarters.
Do get a manicure. Your hands say so much about you. At an office party when you'll be shaking hands, holding drinks and eating, it's best to keep your polish subtle. Essie's pale pink shade Ballet Slippers or Deborah Lippmann's Treat Me Right Treatment Set will look pretty and professional on everyone.
Don't paint your nails fire engine red. I know, I know, it's a holiday! I love red polish too, but your goal at an office party is not to be the life of the party, it's to remain the responsible professional you are. At a work event, with the CEO of your company mingling, neutral nails are the way to go.
