I bought 4 of these in size small. Im 55 and 135 lbs. I like how they're a bit longer than usual so they don't ride up during cardio, weights, or yoga. They fit perfectly over a workout bra. Theyve gone through many weekly washes since I bought them 8 months ago and they're still holding up well. One of them had some fraying/loose stitching at the bottom, but still completely usable. Ill buy 4 more once these die.
