Stila's Eye Shadow Pan ($18), particularly in the go-to shade of Kitten, is a makeup bag staple. "Stila's Kitten eyeshadow is the eyeshadow," said Katygmorris "I'm a beauty junkie and constantly switching brands, colors, etc. If I'm in a hurry I swipe just this shadow on, and I'm good to go. If I'm in a mood to play around with my look, I use this shadow in the dark inner corner of my eye (what I call the bat cave), the brow bone, and in the center of the lid (on top of another shadow). The consistency is super-supple and it stays on my lids all day — even without a primer," she added.
