Summer is the best season to have fun with your hair and makeup. But with a slew of must-try trends like bright makeup hues and flirty hairstyles, it can be hard to choose just one.

That is, unless you're Nicole Richie, who stepped out at the Ella Moss 10 Year Anniversary Celebration in West Hollywood on Thursday night rocking three -- yes, three -- of summer's hottest beauty looks, plus a lightweight maxi dress to boot.

The fashion icon and mom-of-two wore her blonde strands in a French side-braid and sported a bold fuchsia lipstick. To offset the candy-colored hue, she donned a dark, rocker-chic polish on her nails.

Though she helms a fashion empire, the Winter Kate designer insists that her own personal style is much less thought-out. "I don't think it's as prepared as you'd think," she recently told U.K.'s In Style magazine. "I just grab whatever's around and put it on."

The 29-year-old is set to offer her design expertise as a celebrity mentor on NBC's new reality competition series, Fashion Star, where she will join Jessica Simpson and menswear designer John Varvatos.
