S. Eisenburg California vintage mod maxi dress

Unique vintage mod maxi dress from the 50s. I don't believe it's been worn since it has original tags however the lining is ripped some from the fabric near the arm holes, not noticeable from the outside. Great condition but could use a dry cleaning. Measurements laying flat: bust 15", waist 13", hips 17.5", length from shoulder 55", shoulder to shoulder 14". Fabric does not stretch, check measurements. There is a cool slit up the front to about the knees and a bow on the chest. No size tag
