LC Lauren Conrad peach blazer size 12

This is a peachy pink blazer by LC Lauren Conrad size 12. There are 2 faux pockets and a tortoiseshell button. It's a pinky-peach color and the fabric has a sheen to it. The sleeve length stops just below the elbow. There is a stain on the top left shoulder sleeve. See images for detail. I believe the stain is either coffee or soy sauce.
