Retro 2-piece dress

Vintage Sunday, garden dress or church outfit. Rare, Made in the USA. In pristine condition: no stains, pulled threads, pilling, rips, or fading. The labels have been cut out, (purchased liked that), so designer unknown. Both the dress and the jacket are fitted. The jacket and dress are fully lined. Jacket has 2 pockets. Dress is sleeveless. Knee length dress. Hip length jacket. Back "invisible" zipper I'm guessing a 60's era style.
