Since you have noted that the straps keep falling down there are few reasons this could be happening. First and foremost adjust your straps to be tighter. Both the straps falling down and the lack of support means that this bra is not correctly fitting you properly. Most likely, since you are having support issues you could be in the wrong back size. We suggest you go down a back size. We suggest you double check your measurements or be professional fit to establish your correct size.

Style 1891 which is a minimizer which means that the cups are shallow and wider to provide the minimizing effect.

Style 1891 which is a minimizer which means that the cups are shallow and wider to provide the minimizing effect. Minimizers compress breast tissue much like a sports bra does. This compression reduces the projection of breast tissue but can also cause the breast tissue to become wider and flater. You should go up a cup size in this style for a better fit.

Style 1891 is a molded fabric cup not a contour cup or t-shirt which have foam cups. Molded cups are single or double layer(s) of fabric that have been molded into the shape of the cup. This style has a wide elastic back to cover and minimize the look of back fat and could fit tighter which could explain why the fit around your torso was tight.
