Black jeans and a sharp blazer are never going to let you down—word to that—but on their own, they can be a bit lacking in the glam department. Daisy Lowe's sheer red cami vest with tiny repeat-bow pattern, instantly sasses up her black-on-black pairing. So go ahead—do a Daisy and wear a girly vest top under your faithful jeans and jacket, then seal the deal with a bright red lip and manicure. Ta-da! Another knockout going-out look in the bag. BOOM.
