The Blueseventy Podium Open Back features premium Carvico Italian Vita PL fabric made from recycled materials. This fabric is renowned for its quality, shape retention, chlorine resistance and soft feel. Fit Information:The Open Back has thin straps with an very open back design. It features moderate rear coverage. The thin straps are more stretchy and the style of the suit makes it feel like a looser fit. If you're between sizes or at the bottom to middle of a size range, you likely should size down. If you're at the top of the size range, that size should be good for you. Example: Woman 5'7" & 139lbs falls in bottom/middle of size 34, would order a 32.
