As other reviewers have mentioned, Flower Child can be overwhelming. There are so many different rooms, all crammed with stuff. In my opinion, you will only have success if you know what you want and/or just love to shop for antiques and vintage.
The selection is amazing and vast. I think the prices were reasonable, not too high. For vintage, they were standard. As a person who prefers thrifting over antiquing, the prices were much too high for me and my budget, but if I found a perfect piece, it wouldn't be unreasonable. I did enjoy browsing around the store and would recommend it to anyone who loves vintage. Clearly a lot of thought and care goes into what the store curates.
