Happy Birthday, Sierra! May your day be as flawless and fabulous as those DIY projects you effortlessly whip up—seriously, how do you make glitter look so easy? From makeup tutorials that saved us from eyeliner disasters to fashion hauls inspiring closets everywhere (and emptying wallets), you've truly become our go-to guru for all things trendy.

Your recent vlogs have been absolute gems; whether you're sharing cozy home decor tips or hilarious behind-the-scenes moments of everyday life, we can't get enough. Here's hoping this year brings even more success—and fewer mascara smudges—to the queen who taught us confidence is always in style. Cheers!
