Worth it
Size: Large, Color: Blue
Soft material, good fit. A little big but im in between a medium and large so I went large. I like the square neck. Pretty color and good material

arm holes too large, shirt too long, size down
Size: Small, Color: Wine
I am 110 pounds and 5’2”. I ordered a small. The fabric feels awesome. The neck area and straps are perfect. However, the arm holes are quite large. The bottom of the arm hole isn’t straight down, flush with the shirt. It angels outward. If you lift your arms up it looks odd. I should have ordered an extra small. But even if I do that, I still think the arm hole will look odd. I will likely return this or wear it at night or at the gym with yoga pants. The shirt is a tad bit long. If you wear short shorts, the shirt would cover your shorts.

WELL CONSTRUCTED. GOOD STITCHING ON NECKLINE AND SLEEVES. GOOD FOR TALL PERSON.
Size: X-Large, Color: Orange
The Automet women's loose-fit tank top is sized just right for me. I'm 5'11', 200 lbs., 57 years old. I've got some back fat that would be obvious in a tight top. This tank is loose enough to hide my back fat but not too loose. From the front, it does not appear loose at all. It's the back area that has extra room. It has a nice, scooped hem. One special feature is the double stitching on the neck and shoulders. It is well-made. It looks more expensive than it is. I bought the Automet tank top in the color orange. It is NOT see-through, nor is it thick. I live in Arizona, in the desert part, where it gets hot. This tank is thin enough to keep me comfortable from May to October when the heat hits. It's hard for me to find the "perfect" tank. I've tried so many. I feel you would be wise to give this tank a try. Worst case, you return it. I love the orange one so much, I plan to purchase all the colors for this hot summer coming up. I wish all of you the same happiness I have found with the Automet tank top.
