Surprising quality for such a cheap item
Size: 4X-Large Big Tall, Color: Navy White Diamond Geo
Surprisingly good fit. The material is a bit thin and if you're wearing it on a cold day, I would recommend an undershirt. The collars could use a good starching for a more modern look. As it stands with an open jacket, the large collar makes it look a little dated. If you have 20 dollars and need a shirt you could certainly do worse.

Good, but could be better!
Size: Medium, Color: Lavender White Windowpane, Size: Medium, Color: Lavender White Windowpane
+ 3 ⭐⭐⭐ I honestly didn’t expect much at this price it's a good value for money & only if you pay the very discounted price ~$7 or ~$9, The fabric is of good quality feels soft and comfortable right out of the package, with just enough stretch to move around easily during the day. It’s light, breathable, and doesn’t feel stiff like some cheaper dress shirts tend to do. The wrinkle resistant feature actually works only on paper, wrinkle resistant is only a slab of steel or rubber, though after a good steam iron it keeps the shape for a while. After a quick wash and dry, it came out looking presentable without needing much ironing, which is a huge win for busy mornings. The regular fit M is true to size and gives a clean, relaxed look without feeling boxy or too tight. I wore it to work and later out for dinner, and it still looked sharp by the end of the day. Love the Lavender White Windowpane color it is subtle & stylish. It adds a little personality while still being professional. The stitching and buttons feel solid, and after washing, the shirt held its shape and color well. - 2 ⭐⭐ Here is the big critic, I liked the shirt, but it came stained there is a big stain on a sleeve, & I am not sure if it will come off, this is the second on I ordered because the first one was also stained, it seems like some oil or rust ingrained into the fabric, I can understand the first shirt was "used like new", but the second one supposed to be new, yet it is stained, a lot of loose threads, weird seams and stains. As I said this shirt justifies itself only at the discounted price. I did my best to show it in pictures, alas not the way I wanted, it is more visible in person.

disappointing... buyer beware
Size: XX-Large, Color: Lavender White Windowpane
careful there is no pocket? what kind of essential long sleeve shirt arrives without a pocket? I took to the cleaners to have pressed, and just got it back today. so I missed the return window. I am disappointed, and a bit frustrated, it's never been worn and will not be without a pocket....

Great value
Size: XX-Large, Color: Navy White Diamond Geo
Nice shirt for the price. Needed a budget shirt to wear with a suit and this fit the bill. Fits well. Is a little thin, you can see through it if not wearing an undershirt.
