Dioressence by Christian Dior - this is vintate Dioressence.  Pure parfum.  It appears to be unused and full.  The size is what makes this a rare find and collectible - 3.5ml/0.11 fl. oz.  Christian Dior is embossed on the top of the cap and DIORESSENCE is embossed around the side of the cap.  The shape of the bottle itself has a ribbed effect to it.  Bottle, including cap is 2 3/4" tall.
