Calvin Klein blouse

Size M / Runs Small from the chest area , but bigger towards the bottom of the shirt. Brand new never worn. Still has tag. In good condition other than, Shirt does have a yellow stain on the sleeve , that I did not notice when I purchased at Macy’s. I do not want to deal with it but maybe some one can remove it or if you cuff it correctly you will not see the stain. Will lower price because of this.
