Unique vintage burgundy dress

This dress is a unique find. It has no tags and no size. LOL. I found it in a vintage shop and it fit me at the time so I bought it. It’s too small for me now, so I’d say it’s safely a size 8/9. The material is silky and crepe-like, but clearly polyester. The cut is unique and form fitting with a small tie at the waist. If you have a flat stomach you will LOVE this dress. The material is thick enough so it’s not see through - so the lack of lining never bothered me. I wore it probably twice.
