Happy to find these, and that they fit me!
Size: Small, Color: Hot Pink/Oatmeal Heather
After reading reviews, I followed other's advice to get a size down. Glad I did!! After washing and machine drying, they fit good. They shunk enough to fit under my armpits and cover my bra, plus the shoulder length is not too long for my petite torso. I usually have to shorten any tank top straps by about 1/2-1 inch. These are not overly soft like a jersey blend. They are thick cotton, but 100% cotton. Only thing I've noticed so far that I don't care for is the slight bunching on the front of the straps, where it shrunk slightly odd, on a gray one I bought. Thanks amazon for offering these!

Very generous cut & really well made.
Size: Large, Color: White, Size: Large, Color: White
All cotton, 100%. Really well made. Great stitching and excellent weight. Very generous sizing. Lots of online clothing runs small, so I ordered a large and it is much too big across the chest and in armhole size. Should have ordered a medium. Will reorder. But this price was so good that I will not return the large. Will donate them to my local food & clothing pantry. I think they will be great for warm weather, but also for layering in these cold months.

one fits, other too big
Size: X-Large, Color: Navy/Sage Green
The good: made with a nice fabric, a good weight and soft. Color for both shirts is what I expected. I wish I could keep just one shirt. The navy blue tank top fit perfect and was comfortable. Green, same size as the blue one, was uncomfortably big. Arm holes 2 whole inches larger than the blue top. This type of inconsistent sizing is frustrating.

Good quality, not sure on fit
Size: X-Large, Color: Black/Mariner Stripe
I looked at the general comment on this top and it stated frequently returned due to loose fit. My measurements are close to size xl so I figured if they run large/loose then they would fit me fine. My bust is 46 1/2" and I probably should have gone xxl. The tops are snug across my breast and I will have to be adjusting so it does not pull a gap at the side of the arm pit area. However the top is not too snug, also not loose throughout the rest of the body so don't know how I would feel about a size larger. The quality is nice, medium weight cotton. No see through and no falling in creases. I hope washing these in cold and line drying will keep them from shrinking. I will keep these because I do like the quality and length but have not decided if I will order more or not.
