Here is an adorable short sleeve dress. No tags present, but probably mostly or all polyester. Understated and classic, but not boring. White fabric with pinkish red triangles all over, with other geometric designs along the bottom. Zippered back with two clasps at the top. Very thin, sheer, soft, and lightweight. It's in amazing shape and has years 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 laying flat:

Bust 18"
Waist 11" (elastic here stretches to about 19")
Hips 25"
Sleeve 9"
Length 45"

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