I am looking for a look a like outfit of the Heather Mooney character from “Romy and Michele’s High School Reunion” movie.

I would really like to find the exact outfit. I also am trying to find just the black dress I can add the sleeves to later. I am having trouble getting a black dress with this exact look of the high scoop neckline and the arm holes being straight down and closer to the center of the body like a racerback shirt.
