I don't remember wearing this after washing it. It's been a spare change of clothes just in case. However, I think there's a faint discoloration near the left side of the back, so it might have been there from the beginning. I can add more pictures, so please comment if there's anything you're concerned about. When shipping, I may use recycled packaging materials. I'm a beginner and raising a child, so I apologize if there's a delay. I may not be able to check messages frequently and might take some time, but I will try my best to be attentive. Please purchase if you understand that this is a used item. No claims and no returns, please.
