Like it or not, the grunge trend is here for spring and, from the looks of the February catwalks, it will be around through next fall (See Saint Laurent FW13). Grungy looks made an appearance on the spring runways of Dries Van Noten, 3.1 Phillip Lim, and Acne Studios, just to name a few. These designers have moved grunge to the forefront of fashion, and have reminded us that grungy isn't necessarily synonymous with dirty or frumpy.
