Tank tops are versatile layering pieces. Start with a fitted, neutral-colored tank as a base layer. Layer a longer, patterned tank over it for coverage and style. Add a jacket or cardigan for warmth and texture. Experiment with different neckline combinations, such as a V-neck base with a scoop-neck overlay. Create a layered look by tucking the longer tank into the base tank or letting it flow over. Accessorize with necklaces, scarves, or belts for added interest.
