I am normally a medium in tops, and the body of this top fits fine, but the arms are really tight. Especially being a workout top, I would expect it to have more room for muscle. I am 5'10, 150lbs and have broad, muscular shoulders and arms. If this top had more room in the arms it would be perfect. The material is soft and moves well with me. I am a rower and am sensitive to clothing that bunches or gets caught on things - this top is great in that regard. The tie in the back keep the shirt up and out of the way of the seat tracks and looks cute. Overall, if you have a little more muscle on you, size up!

Seems to me less like a workout top and more like the perfect fall long sleeve tee. Maybe I’ll try wearing it on a run once the weather cools off and see how it holds up. A little tight in the arms but not enough that I won’t keep it and wear it.

I wear a size small in pretty much all Senita wear. This is TTS and is super soft.

Great shirt!! But runs small. Go up a size!!

From the pictures, I thought the color would be a true navy...mine looks almost black. fit is fine.
