The Slim Mama is a strapless camisole that attaches easily to your favorite bra. The Slim Mama smoothes and shapes your belly sides and back without constricting your chest or interfering with breastfeeding. It s constructed of the same soft cotton/spandex blend as the original Undercover shirt but has a 360 degree slimming panel starting just under the bust going down to the hemline. Same attachment options & ample length as the original Undercover Mama.
