50s Pastel Mint Green Sleeveless Dress by Westover New York
Side metal zipper. No materials indicated but has the feel of a soft but sturdy cotton type material. Color is good, some of my closeups washed out the color.
No size tag, my estimate is US S/6 based on how dress fit model (Model is 5'10" US S/6, I also tried this on with a belt, I am 5'1" XS and this worked well). Works better on shorter person based on bodice.
39" long, 19" across top shoulders (not a shoulder measurement as this extends over arm slightly),15" bodice. 37" bust, 31" waist, 42" hips - please compare these measurements to a dress you own that fits well. Generous 4" hem allowance.
Flaws: Very minor fade directly at underarms. A few missing beads. I do not have belt for dress, off white belt might work, possibly ivory. A couple pin holes in skirt and 3 small marker tip size fade spots. All are included in photos.

This item is sold from an excellent, highly rated vintage boutique.
