Classic Ponte-Knit Blazer for Women Closets benefits from having a slim-fitting black blazer. They're arguably the easiest thing to throw over jeans if you want to look buttoned-up, and they even can be made casual by going up a size and slouching the sleeves. We love the Classic Ponte-Knit Blazer for Women ($45) because it's made of 4% spandex so it will never feel constricting.
