Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.

Great Fit & Great Price
Size: 3X-Large, Color: White
The material is very nice and soft but not clingy. It’s light weight but not see through in both white and peach. This tank fits true to size and has no gaps under the arm like some other tanks I’ve tried. It’s a perfect layering piece under shirts and sweaters. Very affordable and well made. I’m a plus size lady who is happy with the fit.

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.
