Gilligan & O’Malley bras are sold by Target department stores. This style has been discontinued. Seamless wirefree cups are largely unstructured. An elastic band goes around the bottom and there is vertical elastic in the center between the cups. The material is a modal/spandex blend with sheer nylon/spandex inner slings. Modal is a type of rayon that is very soft and absorbent. Stretch straps adjust in back.
