Stassi Schroeder is having quite an eventful month: Last weekend, the Vanderpump Rules fashionista served as a stunning maid of honor in her little sister's wedding, then on Monday she celebrated her 31st birthday with a special #OOTD homage to her grandmother (and you know how much Stassi loves her birthday), and on Tuesday the author revealed some incredibly exciting news. Brace yourselves, fellow fashion lovers. (Catch up on Vanderpump Rules here.)

In honor of National OOTD Day (which Stassi founded last year), the L.A. beauty teamed up with subscription e-commerce site JustFab to launch the Outfit of the Day x JustFab Collection. That's right, Stassi just made it so much easier to fill your wardrobe with perfect "outfit of the day" options. 

To celebrate her new venture, Stassi and JustFab hosted a Hollywood bash equipped with "Basic AF" cocktails, a peek at her new collection, and of course, a Stassi-level #OOTD photo opp. Beau Clark, Lala Kent, Tom Schwartz, Katie Maloney-Schwartz, and Kristen Doute all attended the event to support Stassi. 

Now, back to the collab. The collection has two sections: Next Level Basic, which includes essential daytime pieces like jeans, blazers, and camis and the OOTN selection, which is filled with perfect date night options like sleek jumpsuits, ruffled blouses, and heels. Each item was handpicked by Stassi herself, and the sizes range from XS - XXL, depending on the item.
