Here is a lovely vintage short sleeve dress. It feels like mostly or all polyester. Great fabric with gray and white striping throughout. Seven buttons down the front. Medium weight to this one. I'm calling it 80s thought it could be 1970s. It's in great shape with lots of life left! Here are the exact measurements. (be sure to reference the last photo to see how I measure dresses)

Here are the measurements:

Bust 21"
Waist 15"
Hips 30"
Sleeve 11"
Length 41"

This item is sold from a vintage boutique in Roanoke, VA.
