Whether you have a dinner, office, or New Year's Eve party to get ready for -- or it's just happy-hour with your coworkers, we've got makeup tips for you! We've asked the experts and they've provided us with everything you need to know to look great this holiday season.

For a Dinner Party

The best way to make lipstick stay put through a meal is to layer your lip products. Lip primers are a good place to start since they prevent feathering and fading. Clinique's All about Lips is a lip primer that comes in a handy pump dispenser and moisturizes in addition to keeping lip color in place. Next, follow these steps:

• Use a lipliner to fill in your lips. Try Prescriptives Lip Coloring Pencil in Wine or your favorite shade. Lipliner will act as a base color and primer for your lipstick. It will last long after your lipstick.
• Apply a matte or long-wearing lipstick such as 3C's Cool Rose, Cover Girl's Hydrating Lip Color in Sugar Plum pink or LORAC's red Catherine.
• After your meal, touch up with a lipgloss to enliven your lips. Try Revlon's Color LipShine in Torch or LORAC's Lip Gloss in Luscious.

For an Office Holiday Party

Sheer and natural makeup is the key to looking professional at any office gathering. But remember, even the most natural, sheer looks will take a few cosmetics to look polished. Here are some easy guidelines to follow :

• Foundation: When you shop for foundation, try products on your jawbone to ensure that they match your skin tone. Makeup artists love foundations from Bobbi Brown, Cover Girl, Laura Mercier, Nars or Sonia Kashuk. Make sure you apply foundation to clean skin.
• Concealer: If you have blemishes, use a concealer one shade darker than your skin to cover them up. (Use a cotton swab or concealer brush and dot a tiny amount of the concealer to mask the blemish.) If you have undereye circles, use a concealer one shade lighter than your skin. Use your fingers or a concealer brush to glide the product over dark areas, blending well. For any other concealing needs, such as hiding broken capillaries next to the nose, use a concealer that matches your skin exactly. Try True Concealer from Skin Alison Raffaele. It comes in seven shades, so you can find a perfect match to your skin tone, even online .
• Finish up with a loose translucent powder. Skin Skin Alison Raffaele has a great one called Transparent Finish powder, suitable for all skin tones. Apply it over your face in sweeping motions with a big, soft, fluffy brush to get maximum coverage and optimum blending.
