Fashion’s Night Out festivities are rife with beauty giveaways, comped updos, and mini-makeovers. But before stocking up on free samples, kick off your evening at Chanel. The French mainstay is introducing its new Les Khakis de Chanel nail-polish collection tonight, featuring three military-inspired colors: Khaki Vert, Khaki Brun, and Khaki Rose. A welcome contrast to the hit-you-over-the-head shades of summer, these subdued earth tones will pair perfectly with the butterscotch and camel hues of the fall collections. Receive a free khaki-colored manicure tonight from 6 to 11 p.m. at Chanel’s newly reopened Soho boutique.
