Here is another Playtex Secrets 4421, this one a 40C. (See a 40B bra here.) These bras tend to fit tight (a 40 band fitting more like a 38). Seamless underwire cups have lace on the outside, cotton on the inside, and an invisible support band around the lower outside edge. The wings are also a stretch cotton. The straps are wide and gel lined for comfort and stretch and adjust in back. See the Playtex video here.
