As longtime “Gossip Girl” fans, we make a point of never missing an episode. This month, we were thrilled to team up with the show to bring our members blockbuster boxes inspired by New York City’s most glamorous events. Prep for a black tie ball with a shine-boosting hair serum, or dress for a trendy book release party by trying out a sparkly liquid liner. If you’re meeting a girlfriend for brunch uptown, make sure to keep a plumping wonder balm in your purse. And don’t forget to book a weekend getaway—we’ve got bright pastel polishes that would fit right in at a chic Hamptons beach party. Not a Birchbox subscriber? Sign up now!
