Here is a lovely vintage short sleeve dress. It feels like mostly or all polyester. The fabric is several shades of green with off white polka dots throughout. Nice sewn in velvet and jewel designs at the front of the collar. Subtle pleat detail to the dress section. Small shoulder pads are present. This one is very thin, incredibly sheer, light weight, soft, and comfy. 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 22"
Waist 18"
Hips 29"
Sleeve 10"
Length 45"
