Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

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.
