What: Jersey dress with feather and crystal detail

Where: Michael Kors (various locations)

Price Tag: $350

Why: Mixing high-end designer items with affordable fast fashion is a popular styling technique, as is combining something casual with something glamorous—both create that perfect “I try but not that hard” look. This bedazzled sweatshirt dress by Michael Kors brings high-low to a whole new level. The heather-grey jersey (ordinarily used for fitness gear) paired with an elegant feather skirt (usually seen on fancy dresses) is pure magic. Wear it with a black leather moto jacket, fishnet stockings, and vintage biker boots for a night out with the girls or with a boyfriend blazer, bright red lips, and sky-high heels to a sexy dinner date. Who says you can’t rock sweats at a black-tie?
