My mother and I will window shop all the time at these stores(because they can be a bit expensive unless you find items on sale) and the variety for anyone is unbelievable
Your so close to your goal and you deserve to splurge. If you know what brands you like then maybe you should try Ebay, since you can get alot of new clothes with the tags still on. And you wouldn't have to pay the premium prices 
Vintage shops are good too, and not to pricey depending on what your buying
