I.B.Diffusion vintage cardigan sweater womens size small

Hello hello ! I've got a vintage one for ya! This is a circa late 80's early 90's cardigan sweater by I.B. Diffusion. European patches. I did include pictures of them all! This really is super cool honestly.. a statement piece today! I'm a sucker for vintage sweaters! Any ways . I did include some discrepancies in the pictures.. (can't stress enough that I don't think they take away from the uniqueness and quality of this sweater) 1. It is missing 1 button. I very well may have one just about exact Match to include with this one. Also on the right shoulder inside there is a hole (not visible while wearing) I assume it was to adjust the shoulder padding. Pictures have a good description but please feel free to ask any questions. Thanks for looking!
