Lululemon Black Button Front Short Sleeve Shirt Drawstring at Hem

Lululemon Black Button Front Short Sleeve Shirt Drawstring at Hem Fabric is nylon or something similar. The logo is on the inside neck of the shirt, as seen in the last photo.  Unable to locate size, but it is oversized medium/large fit for a woman and small/medium fit for men. This top fits like scrubs. Easy care. I have washed in cold water with like colors and tumbled dry with low heat.
