Sleeveless Black White 60s 70s Mod Belted Dress

Go go go in this geometrically patterned black and white sleeveless polyester dress. Zips up the front with a cute plastic diamond zipper pull. Belt at the waist. Very good vintage condition. Measurements laid flat: bust 22" then about the same all the way down. 39" from top of collar to hem. Some minor stains/spots near the bottom that you'd have to try really hard to find. No tags but someone once sharpied their name on the inside? That's not visible on the back.
