We love that this 60s MOD dress works for dinners with the parents and for date night as the overdress can easily be worn without the longer underdress. Medium weight grey wool. The over dress has long sleeves and a simple silhouette that ends with a wide band of fluffy faux fur. The underdress is an acetate tank-style slip with a band of the grey wool that hangs below the outer dress. Both pieces close with back nylon zippers.
