Calvin Klein navy blazer pleat in back single button 4 buttons on sleeves

This black blazer by Calvin Klein is in new condition but has no tags. It is a nylon/rayon/spandex mix with 4 buttons on each sleeve and a single button in the front it has a deep V neckline and faux pockets in the front and a pleat in the back. I can’t find the size but it is 33 inches around the waist, 38 inches around the chest and 26 inches from shoulder to hem (CL1)
