The Escape Bracup Top provides optimal support with its underwire finish and adjustable straps. Perfect for bust cups A - D, featuring double lined fabrication. Designed to be paired with the Escape Cheeky or Kaia bottoms. Generally, we suggest: Size XS = A cup, Size S = B cup, Size M = C cup, Size L = D cup, Size XL = DD cup. However, please consider this together with our size guide, the style of the garment and your full bust circumference.
