I bought these shirts to garden in. I live in an area with a lot of ticks and Lyme disease, so I was looking for some light colored, light weight and long t-shirts to wear while working. These are perfect for that. They are long enough to be tucked in ( and I have a pretty long torso) and light enough weight that I can wear with long pants while working and not get overheated. I bought white, wasabi and sky which are all light enough to easily spot ticks on. The white is a little see through, but the two colors aren't. The fabric does not seem cheap.
I usually buy an extra small as I am a small woman and like my clothes fitted. The small (there is no extra small) fits pretty well around the shoulders and I love the length. It could be a little tighter around the waist for a more flattering cut, but then I expect it might be too small for those who usually wear size small.
