Wool shirt. I believe it's from the 80s or 90s. The size tag is faded, but I think it's M. I bought it used and have kept it at home for many years. Please understand that there may be stains that I can't confirm. It's generally usable, and I think it can still be worn for a long time. I think it's best for those who are used to buying used items. Please refrain from purchasing if you are nervous or seek perfection.
