Rare Vintage Gunne Sax One Shoulder Dress

I’ve searched and searched and can’t find this exact dress anywhere! It’s like the Wild West saloon meets the 80’s and everything about it is bada$$. Zip up corset like torso (has a type of boning). This fits the Sz 6 mannequin perfect. Stain on shoulder ruffle. Will need to be dry cleaned. 3 layer skirt for volume. 💜
