I usually have Gr. 38. Because of the reviews I have the tankini in Gr. 42 ordered and match. ok panties could be a bit bigger, but it's still ok From the bust ago it fits very well, I normally 80D. Small busts definitely fit well in, but with larger is a bit short in size. How the case is in the water, I do not know yet. Am am using the product until now satisfied, except that it comes from China and was probably not human and manufactured with the environment. I have unfortunately used quickly and because "sustainable company" will not be offered anything from, I have to keep it despite foreboding.
