MAC Tropical Mist Lipstick ($16.50 for 0.10 oz.) is described as a “sheer translucent nude.” (I will also note that MAC’s website only describes it as “nude,” which is more misleading than the press release’s description.) It’s a wash of warm beige with a soft, frosted finish. It has a lustre finish. For all intents and purposes, it looks like I put lip balm on, because it looks completely colorless on my lips. As far as dupes go, any lip balm that has more of a sheen than a glossy shine would substitute.
