Love this shirt. It was an extra treat when placing an order for something else, and it turned out to be one of my favorite tops. So glad I added it in my order right at the last minute. I love the color and the super soft material. It runs small. I tend to wear small or medium in other fitness apparel (I'm 5'9, 145). I ordered a large and extra large. Both fit, but I kept the XL so I would have a bit more room to move in it (I wear it sometimes when teaching my kickboxing classes). Fit's perfect, not too large and still fitted enough to look nice.
