Classy Vs. Trashy: Derek Blasberg Crashes Forever 21

Blasberg's take: "When Karl Lagerfeld did a Country-Western Chanel collection for spring, girls went gaga for gingham. Being from Missouri and all, I'm all for it too. But even when you're working with fabrics that are familiar on country roads, you needn't look like a truckstop prostitute."

"While it's true that Balmain has done loads to reinvigorate hooker chic with their strapless mini tube dresses, looking high fashion hooker and twenty-five cent slut is a very fine line. Again, think proportions: strapless on top should mean long on bottom. And as for that sticky metallic fabric: if you squeak when you lean against a wall, maybe try something a little softer."
