This is my very favorite tee from Amazon. It’s workout fabric, so a thicker bouncier feel. It’s non-sheer, as I’m wearing a black sports bra here. And I love the length of the sleeves. It washes out well, no shrinkage. I’m in size large and love this size. It’s loose and relaxed and most importantly I FEEL comfortable in it. The back as a dolphin hem situation and is a touch longer. I would say TTS with a relaxed fit. I have this in three colors! I love a skort in the spring and so I grabbed this one. It’s under $20 I believe I am in the large and it does run small / short. It has short underneath so I don’t really care much about the lenght. It fits well, but it is a smaller fit overall. The material is that swishy athletic material and it has pockets and an elastic band in the back.
