I really like Poor Little Rich Girl. Great brands with a few boutique brands. I always find at least one or two items to buy at a great price. I follow them on Facebook and they put together the cutest posts with adorable outfits. The store itself is nicely decorated and pleasant to shop in.
Most of the people who work there are super nice and helpful. Especially the young man there, he is awesome! Only one time I came across an employee who was kind of rude and acted annoyed to be helping me. Ironically, I think she was a manager or owner.
My only other complaint is that they need to pay closer attention to the condition of their clothes. I have tried stuff on where the hem is coming apart or a button is missing. I don't think it is acceptable to accept clothes in that condition when this is a "higher-end" resale store.
Other than a couple minor complaints, I highly recommend PLRG as a place to pick up a cute, unique outfit.
