You need to be more specific. Are you looking for a store or an online shop? If a store, then where do you live? What kind of lolita clothing are you looking for? Sweet, gothic, classic? Are you a small girl (will fit in brand) or are you a bigger girl (need larger than japanese sizes). And as lolitagirl said, how much are you willing to pay?
You just need to search trough the forum and you will find lots of answers. Make a post of the questions that you have left.
Let me see: I am a bigger girl (size 6-8.... 10 max), and I live in PA. For now, I am looking for a store closest to me. It does not matter to me. I just want to see what I can find. It depends on how much money I have on hand once I am able to get them. Are there any stores that are not online that I can try to look for?
