Vintage ‘70s three piece floral peach suit

This vintage set is so unique. It's a pants + jacket +tank top set from the 1970s. Peach color with floral accents. Pants are wide leg with zipper and button. Jacket is button up, tank top zips up the back. There are a few stains (photos) but I was told these would come out with dish soap since it’s polyester. - set includes pants, jacket, and sleeveless top - vintage, from the 1970s - pants are wide leg - top is boxy with zipper up back - jacket buttons up - size unknown but fits like a medium/large - brand is World Knits - 100% polyester
