Suprise! This style is indeed a jumpsuit. This style is meant to fit oversized therefore the it is suggested to size down if in between sizes. The chestband is made with knitted elastic which allows for an easier tension when taking it off and on. The chest measurement listed above is when the elastic is "relaxed" meaning it can stretch up to 5-8" on top of the relaxed measurement.
