Kristin Cavallari's Must Haves: From a Luxe Espresso Machine to Rao's Marinara Sauce

Cavallari uses her Uncommon Beauty Dust Bag ($5) often, especially when she's traveling. "I just throw all of my beauty stuff in there, and it's just easy to close up really quickly," she says. The nifty and versatile pouch is made from 100 percent cotton and can hold more than just beauty essentials, including jewelry, keys, and any other small travel essentials.

Pro Tip: She loves that this is flexible enough to fit into awkward spaces. "Because it's not a hard shell, you can kind of smush it into places in your suitcase if you need to," she points out.
