I bought this bra in a size 34G.  It is very comfortable and fits well.  I believe that it runs true to size. My measurements are 33in underbust and 42 inch overbust. The gore does sit a little higher on my frame than it does on the model.  This bra works for most of my shirts but does not work for the ones that show a lot of cleavage or have a really deep plunge.  Basically, find something else to wear under revealing evening-ware.
