below average value but decent quality on this 95.4% Polyester, 4.6% Spandex dress shirt
Special Size: Black Buttons, Size: Large, Color: Sky Blue, Special Size: Black Buttons, Size: Large, Color: Sky Blue
At $20 when I picked this up, it was overpriced for what it was. I'm held accountable to the value assigned to me at the time I select to review it, so I review the value based on what was assigned not on what it later becomes if they discount it. As I write this I can see it is in a value range it should have been for me, but I'm still reviewing it at the $20. That's overpriced on a 95.4% Polyester, 4.6% Spandex shirt (i.e., non-cotton) and so the value here is a 1/5 or 2/5, say 1.5/5 for it. In terms of quality, this is a poly dress shirt. Still, I'd call this a 4/5 for what it is.
The standard is cotton, and in my experience, as someone in ties and collared shirts all day, I would note that I do prefer a 95 cotton/5 spandex blend, with the challenge that its not the most wrinkle free material. This blend, 95 poly/5 spandex, is a very wrinkle free and smooth feeling material. Poly has better durability than cotton despite feeling thinner, because it won't fray as much. That said, even though it's lightweight, poly will make you hotter because it doesn't breathe like cotton. It feels light, so you think it is going to be cooler, but in practice actually isn't really if it's a hot day. It can make you sweat more.
That said, many people like poly blends for the ease of maintenance. I've given up dry cleaning, just too much, and I do like to avoid an iron, so I tested this out because of it. For me this fit well. I ordered a large (typically I prefer to wear a 16.5/34/35, and I'm 5'11, 185) and this fit well. It's not a slim fit (tapered bottom) for those who might complain about extra material. But it fit well. I put it through both the wash and dryer. It did not shrink (poly usually doesn't) to be out of size, but was fine, and of course came out without wrinkles. The collars have no stays, these poly shirts hardly ever do, but I have found they mostly remain flat, since the material doesn't tend to wrinkle, and thus my points stay in place just fine.
At a 1.5 on value and a 4 on quality, this is a 2.75/5 average for me. Again, value plays a big part for me. So, full disclosure a better value would have raised my rating on this. But hopefully, based on what I covered above, you have enough to figure out if this shirt is worth it to you or not.

Nice dress shirt
Special Size: Black Buttons, Size: Large, Color: Grey
This shirt is a super soft and an awesome style, which I really love. The material is a soft cotton and that doesn’t irritate my skin. It is breathable, but also keeps you relatively warm. It’s very nice looking on and would be okay for everyday wear. It has been used many times going out with jeans or shorts out. I wash and dry it regularly in a machine and still looks just as new as the out of box condition. There is no pilling, fabric change, or shrinking. The style is flattering, cut well, and runs true to size. Other shirts owned feel similar to this one, which meets expectations and is a nice shirt for the price. I do wish it had a pocket though. Ultimately would purchase again.
