Happy birthday, Aries! This sign is the "baby" of astrology because it kicks off the zodiac, but if you think it could be a docile infant, think again! This is a feisty fire sign, bringing adventure, confidence, and courage wherever an Aries lady goes. Think of Sarah Michelle Gellar, who was drawn to the role of Buffy Summers. Sarah Jessica Parker's entrepreneurial nature has brought her immense success with her fragrances and clothing line. And Mandy Moore captures the essence of this fire sign's versatility by turning Rihanna's "Umbrella" into a smoldering version.

On the other hand, Aries can be a big ol' baby when it comes to getting things their way. And if you're looking for a diva attitude, you'll get it (Mariah Carey, Diana Ross, Celine Dion, Aretha Franklin, and Fergie are all rams). To find the middle ground between self-esteem and selfishness, Aries should make an effort to ask for opinions — and listen to them, too.

For Aries-specific beauty and shopping suggestions,


What works if you're an Aries: Aries rules the head, so make a statement with your hair. Some Aries women, like Jennifer Garner and Reese Witherspoon, look wonderful in neat, classic hairstyles such as chignons. Others, such as Mariah and Fergie, like to be the first to try a look — so take after them by experimenting with bold makeup and extravagant locks. Either way, red is your signature hue, so don't be shy to wear it. Just remember that a little goes a long way, so pair it with simple neutral beige and champagne colors.

What doesn't: "Granola" style. Even if an Aries is passionate about saving the earth, she's more likely to invest in some paraben-free, organic products (or go with a DIY treatment) than forego pampering altogether.
