Here is a sharp vintage dress. This is predominantly polyester I would guess, based on the feel. It's brown, with tan at the bottom. The whole front side is pleated, while the back is smooth. It has loops for a belt, but no belt itself. The tag says size 12, but here are the exact measurements. (be sure to reference the last photo to see how I measure dresses)

Here are the measurements:

Bust 19"
Waist 22"
Hips 22"
Length 40"
Arm hole 9"

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