Jean Lang Vintage Geometric Dress

This long sleeve vintage dress by Jean Lang comes to us from the 50s or 60s and features a rich geometric pattern in green, white, and black. The sleeves are 3/4 length, and the hem falls to the knee. There is a zipper and hook & eye closure in the back, and the fabric has a bit of stretch to it. For example, the waist is measured as 17" but can stretch to 19". Both labels are still in the back of the neck. This dress is not marked with a size, but it fits like a medium. I'm wearing the dress in the second picture and I'm a size 4 (there is space in it). Please use these approximate flat lay measurements to ensure the best fit: Pit to pit: 19" Waist: 17" Hips: 20.25" Sleeve length: 21.75 Total length: 38.5"
