Size tag is unreadable. Measurements indicate it's a Men's medium. See photos for measurements. Thanks for looking at my listing! MEASUREMENT: Please see photos. FLAWS, if any, are pointed out by a ruler. All clothing items have been cleaned. I try to be environment-friendly, which is why this order may come in recycled box or packaging. After I receive payment, I will ship your item within the stated handling time. If you encounter any problem, send me a message so I can address it. Thanks!
