I might need to go back and buy this in every color. It's such a versatile piece to own because it looks nice with jeans, shorts, or a skirt, but is also perfect for outdoor activities. I have worn this hiking a few times and it's a great length for a pack, wicks well, and is extremely soft and comfortable. I found this to be true to size and bought a medium. I'm about 5'7" and athletic build (broader shoulders/back/upper arms).
I love this tank and have purchased it in almost every color. I wear it for working out at the gym, running, or just wearing around town. I got it in the same size as my Kuhl jackets (small, I am 5'8" and 125 lbs), and it fits perfectly loose without gaping. The fabric is light but substantial and dries quickly. Love the colors--striated dark and light. Can not recommend enough!
