Vintage L'AGENCE Silk Leopard Cocktail dress Size Sm

I adore this dress - it is so flattering and the details are on fire! Shoulders have a decorative elastic trim with raw unhemmed silk at shoulders Gathering at waist with also raw unhemmed silk The arms, neck and bottom of dress are hemmed silk Zipper at back It cinches you in just the right spot, and the gathered waist that is pleated up into the bodice is perfect for small or busty women I cannot find the size of this dress, but I am 5'7" and 138 in the image above. So my guess is a small since that is what I am in other L' Agence dresses and clothing.
