2 things sold me on this nice tank. First, it's bamboo. I like the feel of bamboo - I think its a cooler material and it's easier on the environment. Second, I love the lace!! It really dresses up a simple tank! I did order up 2 sizes. I wear a L normally, but I didn't want this to accentuate my love handles. The XXL fits looser and stays flat and doesn't cling. I've worn it alone a couple times and have gotten compliments on it. I'm really happy with it and wish it came in more colors!
