About a woman with a great pair of breasts in a wet white t-shirt. A set of A's through very large breasts (as long as they are not sagging down to the knees) look amazing in a wet t-shirt. Having perfectly hard slightly large nipples are a huge bonus.  

I am a huge fan of natural breasts and would take a nice set of natural breasts 100% of the time over enhanced breasts but in a wet t-shirt I can fall in love with enhanced breasts also.
