If your DD$$ has the budget to match her tastes, then a trip to Mall at Millenia is probably in the cards. Lots of top name retailers there; all the way up to Prada and Tiffany. Hopefully there are some good sales on at the time. Otherwise, the two Premium Outlets are still probably your best bet. There are a few differences between the two, so have the ladies decide which one has the better lineup, or hit them both. You can also check out the lineup at Lake Buena Vista Factory Stores (lbvfs.com) to see if any of the stores there are of interest to them. It is a much smaller outlet, good for a quicker shop.
All of the above have mall directories available online. Let the ladies review and choose.
