I have this top in a different colorway (narrow blue and white stripes) and love how it is both incredibly light-weight and yet, not see through. I usually like to tuck my shirts, and since this one is so light-weight I can easily do so. I do need to consider visibility through the arm holes though, they dip low enough to show the top of the band of my bra, so I usually wear a black bra, so it looks more like an undershirt. I have had my shirt for a long time (long enough that I bought it in a sz. small) and it has stood up to many washings. I am 43, 5'3" 155-165lbs and usually wear a sz. Large or 10 now. Oddly the small fits fine and if I order it again in another color, I'll probably order whatever size is available, since the cut is quite accommodating.
