When she was created WW looked far more like what might be considered the average body shape for a women of the time. She was drawn in what could be considered in some ways a far more realistic way.
These days she is portrayed with same huge breasts and 'shapely' ass that nearly every other super-heroic female figure seems to be equipped with. I know she is unbelievably strong but does that mean automatically she should be so well equipped in the breast department, because as with Power Girl that's what it seems to equal. The stronger you are the bigger your breasts.
To me it's slightly disappointing that such an iconic character is given such standard body shape, well I suppose we should be thankful for the fact that at least she has far more of the classical Greek look than when she started out.
