Has anyone here bought this brand before? I am looking for a good dress for my 7 year old daughter (for a wedding) and I have fallen in love with their dresses. The only problem is that on the website the sizes are either 6-7 years or 8-9 years. I am unsure of which size to get! I was wondering if anyone could tell me what they are like for size?? I have looked at the size charts and they don't really help - she is in between basically. Anyone have experience with this brand?
