Neil Bieff Sequin and Bead Blouse 1980's

This one is special and rare. 1980's Neil Bieff Sequin and Bead Blouse Fully multicolor sequin embellished sleeveless silk top Abstracted floral patterned sequins Fitted at waist Plunging V back, hook and eye closure at lower back Can be worn front to back Silk lined 1980's Neil Bieff, made in India From my research this seems to have been made for Nieman Marcus, but may date from before they were produced for Nieman Marcus, as this one plunges all the way to the waist in back, and has no NM Tag, or evidence there ever was one. Also the inside silk is nude, rather than turquoise. Two miniscule issues, that I had to search for. One bead missing near zipper, and two iridescent sequins on shoulder, as pictured. There may be more, but none I found. Flat measurements as follows Armpit to Armpit 19" Waist top 13.5" Waist middle 12.5" Waist bottom 14.5" Length 20" Please ask any questions.
