Free People long sleeve size medium

Hello hello I am selling my used long sleeve shirt womens size medium by Free People. The shirt is white with blue printed sweater cuffed and bronze buttons. The shirt is in great condition BESIDES the stain on the middle of the back of the shirt(in pictures) which I HAVE NOT attempted any skilled tricks of the trade stain removal! Which I'm sure is possible. The shirt is just in too good of condition over all to toss out! Hopefully it will make a new home! Any questions feel free to ask! Thank for looking!
