Nice Shirt, but not "Wrinkle Free."
Color: Blue, Size: Large, Color: Blue, Size: Large
I like the weight, feel and fit of the shirt, however it is NOT "Wrinkle Free."
I put the shirt through the wash to see if that might fix the issue, but it's still wrinkled and I plan to return it.
(Perhaps - if I ironed it - it would stay wrinkle free after that, but I have a closet full of truly wrinkle free shirts and pulling out the iron simply feels like too much effort.)

Not Wrinkle-Free at All — Very Misleading Description
Color: Orange-pink, Size: Medium
I specifically purchased this clothing item because it was advertised as having “Wrinkle-Free Fabric.” Unfortunately, the actual result was very disappointing. After washing and drying it according to the care instructions, the entire garment came out covered in wrinkles. There was absolutely no sign of any wrinkle-free or anti-wrinkle effect. Every wash still requires ironing, which seriously contradicts the product description.
If you are buying this item because of the “Wrinkle-Free” claim, I would recommend thinking twice. The quality does not match the advertising at all.
