This style, apparently recently discontinued, is a cooperative venture between Maidenform and Delta Galil. The plastic underwire is quite soft and flexible. Seamless molded cups with light foam padding. Hidden elastic in the wings. Stretch straps adjust in back. The material, inside and out, is a very soft brushed polyester/spandex. 38A is a fairly rare size- few girls bras come with bands this big and few adult bras come with cups this small.
