I used the size chart provided by the seller to decide on the size. It fit beautifully and is comfortable and beautiful. The roses are very vibrent. I loved the length of the skirt of the dress because it comes to just below my knee which is exactly what I was looking for. I wore a petticoat underneath the dress to keep the skirt super full, but I feel that I totally could have gotten away without one! Overall this dress exceeded my expectations.
