Karen Kane XL back drape black blouse

Karen Kane XL black sleeveless blouse. Front is double fabric and v-neck. Back is single fabric with a strip that connects shoulders and evening wear type drape. Flowy generous cut & non clinging. Made in USA, 100% polyester, dry clean or hand wash. Underarm seam to seam 21.5”. Looking closer, I see 2 micro threads on front. Must be small pick but no hole or thread gather. I won’t cut them off. I took extreme close ups. Honestly they are hard to find even knowing they are there.
