Angelica Swimsuit Stripes White and Navy

I like the style which is why I bought it However the material is not very stretchy as one would expect from a bathing suit. I expected it to be firmer . Unfortunately, it does not support a bigger bust and the breast keeps "falling" though the hole. I have only tried it on so far so can't comment on how the fabric behaves when it's wet as I am still deciding if I will send it back or keep (Size 8-10AU, 10 DD to E Bust, bought size 10)
