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.
Good quality product, no damaged ones, also bought the skirt/trouser ones and the coat ones. All excellent. Wardrobe looks brilliant now. If your a storage demon like me, these are worth every penny, and will last for years.
