The Acacia Top is our classic triangle style, designed with adjustable straps and a tie-back closure, allowing you to adjust the fit to your liking. The perfect tanning essential. 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.
