A liner is a line and a shadow is a shadow, right? Not if it’s 2007. Liners have come a long way. We’ve seen duos with a shadow on one side and a liner on the other, ho-hum. The latest twist to the standard is from SUSAN POSNICK. Her ColorEyeDefine Eye Liner-Eyeshadow ($26 @ beauty.com) is an angled liner on one side and a self-dispensing shadow on the other. No need to sharpen, or refill either side so it’s great for the purse. Six duos available.
