I’m selling these beautiful tennis T-shirts due to me now being a size small but when I purchased these I was a medium. They are a mixture of mainly cotton and some polyester but feel very soft and have a nice thick quality to them. The white one has a very faint mark on the back which is shown in the photos which is barely visible but I rather mention it. The T-shirts are beautiful and as they have sat in my closet for about 15 years as I forgot about them, will have been since discontinued. I thought it would be nice to sell them as a matching pair!
