YSL Plum Tunique (90) Rouge Volupte Shine Oil-in-Stick ($38.00 for 0.11 oz.) is a medium-dark plum with subtle, cool undertones and barely-there pearl. It had medium color coverage in a single layer, which was as described, that applied evenly and smoothly across my lips without tugging. The texture felt lightweight, emollient but not slippery, and comfortable to wear. I was most impressed by how it seemed to camouflage most of my lip lines and didn't settle into them. It wore well for four and a half hours, left a faint stain behind, and was hydrating over time.
