Day-To-Night Beauty

Nicole Richie

By Abby Gardner

Don't knock the simplicity of a high bun. It keeps your hair out of your face all day long and can be dressed up with a simple red lipstick for evening. Instant chic.

Eva Longoria Parker

Eva's half-updo is perfect for a day filled with meetings where you need to dress to impress. It works with a business suit and a cocktail dress. Plus, glowing skin, long lashes and a nude lip are always office-appropriate.

Ashlee Simpson-Wentz

Long side ponytail: check. Glossy coral lipstick: check. Effortless beauty: check. We love polished but not prissy.

Eva Mendes

A good blowout goes a long way. Like, say, from 8 a.m. until midnight. Spend that extra time in the morning when you know you're going out. You'll be so grateful you did later that evening.

Jennifer Hudson

Jennifer's look is focused around the blunt bangs and those rosy cheeks. We love that it says "Don't mess with me. Seriously." This will come in handy with tough clients at work and pesky barflies at happy hour.

Jessica Biel

It's amazing what a few pieces of hair framing the face can do. They give a little something extra to what is essentially a mussed ponytail. If you're not much for makeup, stick with a clear gloss on the lips. (And if the accessories feel like too much for work, then add them before you go out.)

Liv Tyler

Liv proves that red lips can work for daytime — you just have to pick the right one. Something more along the lines of a stain won't make you stand out at work but will still look special enough for evening. Keep the eyes almost nude and you're good to go.

Jessica Alba

If you're anything like me, you pull your hair up by mid-morning every day. Try a smooth, low chignon paired with a pinky gloss a la Jessica here. It's a classic look that will always be in style.
