VTG Hot Pink Dress

I could be wrong but this looks late 70s to me. Amazing black geometric pattern on a hot pink magenta dress. Long sleeves, shoulder pads, elastic waist, great seams + shallow pleats on the skirt. Zips up the back, bodice is lined. 100% polyester, made in the USA. Color is slightly darker than these photos. Excellent condition. Vintage size 14, use FLAT measures: Waist 14" with plenty of stretch, up to around 20" Hips 23.5" Pit to pit 20" Arms 20.5" Shoulder to waist 18.5" Waist to hemline 26"
