Vintage 1960's Shifts Internationale dress

Pristine vintage 1960s Shifts Internationale of Miami shift dress. Blue dress with a mint green and white floral pattern, outlined with a delicate white lace pattern around the neckline and bottom of the dress. The front of the dress has a slit panel, with slits on both sides. Easier to see in side photos I took. Zipper up the back, and sleeveless. This dress has no sign of wear other than the zipper loosing some blue on it. The lace and fabric is in perfect condition for being truly retro and vintage. I think it is cotton material, with no stretch. Measurements bust: 17" waist: 15" length: 36"
