Best white tshirt ever! Will have to buy more
Color: White, Size: Medium
Top is great, better than the expensive designer top I bought. Fabric is so very soft, not super thin and just the right size. I bought a med and it fit perfectly, just right under a jacket or separate. It’s pure white with some stretch if you want a. Lose fit.

Unbelievable shirt for the money!
Color: White, Size: Small
Soft and cozy yet sharp and finished. Would definitely highly recommend. Went back and bought two more. Comes out of the dryer without a wrinkle. The color on the brown is rich and looks good dressed up or down. Definitely a great T-shirt at a fantastic price.

Love these and perfect for European Spring
Color: White, Size: Medium
Very nice for travel. They rolled up perfectly and fit easily into my compression bags. Best of all, they didn’t wrinkle after a 14-hour flight. The material is soft and heavy enough for spring weather in Porto. I wore both colors there in April. I got a spot on the brown one, and it came right out. It also dried quickly without leaving a water stain. I probably wouldn’t wear them in Georgia during the summer. The white is more of a cream color, and the brown is a beautiful chocolate brown. The sizing was accurate. I’m 5’6” and 150 lbs, and the medium fits loosely without looking baggy. It also works well worn untucked over pants. I would definitely purchase again.

Great for the price but not perfect
Color: Light Green, Size: Large, Color: Light Green, Size: Large
I have this shirt in two colors. Can’t beat the price! The shirt is a good thickness (the white is NOT see-thru) and fit well. It holds its shape when washed. Looks great with a cardigan or blazer, and it’s very comfy. Not too tight, not too baggy. I took off one star because it pills badly (see pic - this was after wearing only twice). My fabric shaver took care of it easily, thankfully. It’s also hot. The polyester doesn’t breathe. But again, for the price - great option for layering on a less hot day. For sizing, I’m 5’6, about 185, and a 38C bra. The Large fit me perfectly.

Classy t-shirt
Color: Black, Size: Small
I bought one of each color that was under $8. They are soft, lined with silky material, no wrinkles and are appropriate for casual work or looking out together running errands. They are somewhat structured and feel expensive. Best find for summer over anything I’ve found so far. These beat every high end tee shirt by far in quality, fit and price!
