It's hard to imagine a time when Nicole Richie wasn't the poster child for modern boho-chic, but before she became one of Hollywood's coolest moms, a designer, and something of a style icon, Nicole had a thing for bold colors and body-con silhouettes. Since today happens to be Ms. Richie's birthday, we're celebrating with a look back at her fashionable transformation. Nicole's style has seriously evolved from the hot yellows and pinks that once dominated her wardrobe to a sleeker, vintage-inspired style that we can safely say is a vast improvement. Now that she's a mama, Nicole sticks with her boho vibe but often switches it up with sexy, streamlined LBDs and dark hues. Click through to witness Nicole's fashion metamorphosis for yourself — and wish the boho beauty a very happy birthday!
