Our Editors Have Tested a Lot of Products, but These Are Their Favorites For September

"Kim Kardashian collaborated with her lifelong BFF Allison Statter for this KKW x Allison B.F.F.A.E. Eyeshadow Palette ($30), and it's currently one of the most used items in my makeup bag. The darker colors add definition to my crease without looking harsh, while the matte and shimmery cream hues are ideal for highlighting. But the crowning glory of this palette is 143, the lavender shade. I put it across the center of my lid and love the metallic finish. It adds personality without looking kitschy or overly trendy." — Macy Williams, senior editor, shop
