Amazon calculates a product’s star ratings based on a machine learned model instead of a raw data average. The model takes into account factors including the age of a rating, whether the ratings are from verified purchasers, and factors that establish reviewer trustworthiness.
I love this dress and bought it in two colors. It fits true to size without being too clingy and can easily be dressed up or dressed down. It is also not super short which I find can be an issue in many Amazon dresses. Highly recommend!
