Jennifer Garner has done it again — and by done it again, we mean wear her all-time favorite leggings. Correction: These are Hollywood's all-time favorite leggings, and for good reason. They give you the best butt ever (no squats needed).

If you didn't say "Spanx Booty Boost Leggings!" after reading that last sentence, we're saying it now. Garner, who's been a longtime fan of Spanx and has praised the brand's famous Bra-llelujah Bra in the past — which happens to be one of my favorites, too — is also a die-hard Booty Boost fan. She's worn various versions of the butt-enhancing leggings that Reese Witherspoon and Kourtney Kardashian, as well as myself, also own, and the fact that she just stepped out in the navy blue version further proves her devotion to this particular pair.

She owns them in classic black! She owns the star-printed version (which is no longer available)! She probably owns the cropped version, too! And now she definitely has the pretty navy blue colorway in her closet that we're adding to our cart right now.

If you haven't tried the Booty Boost leggings, you're sorely missing out. But the good news is, if you don't yet have the Garner-approved bottoms, you can in a matter of days. They're still in stock at Spanx (though the Booty Boost has been known to sell out pretty quickly), and they cost $98. They're also available in sizes XS to 3X and in the aforementioned black and blue. The brand also just dropped new fall colors in their ⅞ Booty Boost style (a.k.a. a shorter hem) that are definitely worth checking out.

The butt-lifting leggings are a great addition to your workout attire — or really, everyday wardrobe — because they obviously boost your butt in seconds. What's more, they're made of a super-soft, moisture-wicking, sculpting fabric that feels so comfy on and makes you look so good. (Whenever I wear mine, my confidence quadruples.) You also won't have to deal with any camel toe, because of the seamless front, nor will you have to figure out where to store your keys while you run because of the small back pocket.

There's a reason these leggings have become so popular in Hollywood (and among the editor scene). They're game-changing, plain and simple. Shop all the iterations of the beloved Booty Boost leggings below.
