Part of the problem is that the stores are smaller here than up north. Our Macy's is one quarter of the size. Fl is casual too.
If you are into Florida style go to Bealls they have really cute Fl style dresses like Tommy Bahama casual. Bealls is the Florida store and reasonable.
I don't know where you're from but I'm from Philly and it's all malls too. Downtown has a bit more.
I see stores like Anthropologie and Bloomingdales at the Millenia place so maybe if you say where you shopped up north then you can get better advise.
If all else fails take a trip to West Palm Beach they have Norstroms and some boutiques. West Palm Beach is a fun place to visit especially downtown city place. If you're wanting to spend bucks go over to Worth Ave in Palm Beach. It's like Rodeo Drive.
Even if you don't buy anything, you'll have fun window shopping there if you're a shopper.
I was looking for a particular bag and had to go down there for it.
