Technically a night gown but could be worn as a dress as it’s long enough (I’m 5’6 for reference), you will just need a slip under it. It’s sooo cute, pics don’t do it justice. Fits like a medium or small but could fit a variety of sizes since the hips are free flowing. Measurements in pics, approx. pit to pit is 20.75 inches and length is almost 33 inches. Disney brand, not Doen.
