There are buttons on the back that go all the way down that personally in my opinion ruins the style!! Will be returning because that is not what I expected.

Faded Glory 😂 3.5 rating
Size: XX-Large, Color: Black-red, Size: XX-Large, Color: Black-red
Sooo faded I didn’t even want to try it on. And very dusty and ashy looking but only the red. It’s as if they had someone wear and wash it and return it and they took the red side and buttoned it onto another color and shipped it out. Guess these sellers like faded clothes. I wouldn’t buy certain colors seeing ppl talking about how the color doesn’t even last even upon its arrival. But if you have dye it’s your best bet to have some on hand when you order or even good for DIY projects.
Good thing is I did try it on and it fits and feels like good quality with good weight to it. May have to go up a size I’m a female with big breast. Seems like it may last, just not the color. Good stitch work buttons seem sturdy. Yea these shirts would be great for DIY work
