A sweater in either a long or short sleeve can turn any dress into a skirt. I love this idea because it makes the most of the items in your closet.
Below I paired a low cut leopard dress with black peep toe heels and gold jewelry for a night time look. For work I paired the same dress with a red sweater in a lightweight material and nude shoes (so not to distract from the printed dress and colorful sweater). All items below are from Forever 21 and below $25.
