Taylor Hill's Must Haves: From a Béis Backpack to a Hyaluronic Acid Serum

For Hill, this plush Original Casper Pillow ($59, originally $65) is both a nighttime and travel essential — the supermodel claims she takes it with her wherever she goes. "When you first buy it, it comes in a roll — like a tube. I don't know how it works, but I've been in a few situations where if I know I'm gonna be somewhere for a really long time, I'll get a new [pillow] in the tube still, and I'll bring it with me," she says.
