I had been eyeing this dress for over a year but was unsure about sizing and was hesitant.  Based on other reviews I thought that it would run small.  However, I am between a size 12 and 14 and ordered an XL because another reviewer said that she wears a size 12 in the Large is tight on her.  There must be a big difference between a Large and an XL because the XL runs big in the chest.  The bodice gapes and would be better for a bigger bustline.  I considered exchanging it for the smaller size but would rather have it be too big than too little as alterations have to be done on the length anyhow, so I will have the bust taken in at the same time.  Other than the size issue, the dress is absolutely stunning.  The included petticoat and hoop help make it look very authentic like a "real" princess.  It is a gorgeous shade of blue and the metallic touch in the brocade makes it look expensive.
