Minimizes up to 1" without flattening you and prevents "popping buttons" on your favorite shirts and blouses. Non-padded for less bulk. Seamless, unpadded underwire cup has a silky, stretch opaque lining for natural shape and feels cool. Stretchy seamless cups provide a custom fit for each breast and are a great solution if you're not quite even. Inner side panels in larger sizes (see note below) give added side support. Underwire is encased and double lined for comfort. Encased elastic top cup edge gives a more custom fit. Bandless front is less bulky for short-waisted women. Center panel - lower for a more streamlined look with breathable mesh, "C" logo charm and satin bow. Arched for high tummies. Sides and back have sewn-on elastic at edges for a more custom fit. Seamless sides lie flat under clothes. Center pull, narrow elastic straps are fully adjustable in the back with coated metal hardware. Back coated metal hook-and-eye closure. U-shaped back helps take weight off shoulders for a custom fit. I do not smoke; however, some buyers have reported that my items have a smoke smell. If this is a concern for you, please consider shopping elsewhere. I am frustrated by the returns related to this issue and receiving neutral or negative feedback for something that is untrue. I do not have control over how these items were stored, nor do I know their previous environment. Thank you for your understanding.
