A long tank top extends past the hip and solves the coverage problem that regular tanks create when you tuck them in or bend forward. The extra length means the piece stays where you put it and does not ride up under layers. This works beautifully under shorter pieces or when you need something that anchors your outfit without being visible. The fabric should be substantial enough to hold its shape through the day but not so heavy that it adds unwanted bulk. Cotton blends work well for this because they have enough structure to maintain the longer silhouette. These are the tank tops you wear when standard length creates constant adjustments.
