I just received this dress in petite extra small. for reference, i am 5"7 and 118 pounds. to answer the previous reviewer's question, the regular size of this dress runs long. if you want it to look like the one in the video, then order it in petite. i personally love the style and the material. however, the inside slip is very short with the petite given my height but this can be solved by adding a half slip underneath it.
