The $8 Item Law Roach Uses to Prep Stars for the Met Gala — Plus 5 Other Must Haves

"I love caviar and Ruffles," Roach says. "It is the perfect way to celebrate with family and friends." You can shop Caviar Russe's Caspian Sea Classic Osetra Caviar ($165) in all different sizes, depending on how big the party is that you're hosting (1.75 ounces is recommended for one to two people). The flavor boasts a full and nutty taste, and pairs well with everything from chips to mini pancakes. In a pinch? You can purchase it on the site for next-day delivery or pick it up if you're near one of the boutiques in New York or Miami.
