"Conservative" in Speedo swimwear indicates a lower-cut leg line, as pictured here. This style is also available in plus sizes. Speedo is the competitive swimmer's choice, with high necklines that do not catch water while lap swimming. Tank suits may be worn alone or underneath loose-fitting modest swim dresses for added support. The Kneeskin styles, designed for competition swimming, cover to the knee. Sizes fit closely, so order the largest size that fits all your dimensions on the size chart.
