A pair of classic pumps would be nice.   I don't want her wearing sneakers or flats with evening wear :)    Some teeth morphs as well to make teeth disappear (they get in the way of some expressions)  and smaller.  What I like about V4 is that you can adjust the scale and height of her teeth and they can be selected separately.  A narrow-shoulders morph that will work well with poses for a more petite look would be a welcome add-on.
