Number one recommendation for her, for better clothes fits and to take advantage of her PBM (partial body morphs) is Morphing Clothes sold here, as there are hardly any clothes that come with her PBM fits, if they come with S4 fits at all, they're usually FBM (Full Body Morphs).

This way you can also fit old clothes to her as well.

Got an S4 character coming soon (If Renderosity would hurry up) that takes advantage of S4 PBM morphs not only to look gorgeous, but also for a young look (3 ages).  So clothes fits is a must have.
