This is a lululemon run swiftly tech short sleeve top in good used condition! The only flaw is that on the left sleeve there is some imperfections of the fabric. I’m not sure if it was flawed when I purchased it or if something else got on it. When worn it really does blend with the texture of the shirt. Size 10. Please review pics 5 and 6 as well as the others. Thanks so much!!!😊
