Nice Quality, Great Fit, and Very Comfortable!
Color: White, Size: XX-Large, Color: White, Size: XX-Large
I ordered this shirt for my husband, and he is very pleased with it. He says it is a really nice shirt that fits true to size and looks sharp. The fabric has a great, quality weight to it that gives it a structured appearance, making it versatile enough to easily transition from a casual day out to a more business casual setting at work.
The biggest selling point for him is how comfortable it is. He mentioned that it feels great against the skin and offers excellent mobility throughout the day, thanks in large part to the classic back pleat design. The chest pocket is a nice, practical addition, and the classic Oxford style looks great right out of the dryer. It is a well made, reliable closet staple that he is already getting a lot of use out of, and we highly recommend it!

An excellent button down that fits well, looks great, and feels as good as it looks.
Color: Navy Blue, Size: X-Large
From the office to dinner and the to church on Sunday, this is a perfect shirt for any situation.
It even looks great worn open over a t-shirt with a pair of jeans and boots or tennis shoes. Who said a nice button down needs slacks and dress shoes?
It is a cotton?polyester blend so it is lighter weight than a standard cotton oxford. It also isn't as crisp or harsh and it doesn't wrinkle nearly as bad either.
The sleeves are a standard long sleeve but they cuff well. The shirt looks great when cuffed too so that helps when it's hot and humid.
There isn't really any stretch to this shirt but that isn't a problem becuase it is perfectly true to size. Just follow the size chart and fit is near guaranteed.
For only 20 bucks, basically, (22 to be exact), this is a great choice for any situation when a nicer than completely casual look is desired.

Husband approved
Color: Khaki, Size: X-Large
I got this one for my husband too, and it is a really nice shirt. It has that classic Oxford look that works for a lot of situations, whether he is wearing it for work, dinner, church, or just trying to look a little more put together.
The fabric feels comfortable but still has enough structure that it does not look sloppy. It is not stiff or scratchy, and the fit looks good on him without being too tight. I also like that it holds its shape well and does not seem like it will need a ton of fussing to look decent after washing.
The style is simple in the best way. It pairs easily with jeans, chinos, or dress pants, so it is one of those shirts that can go a bunch of different directions depending on what he wears it with.
Another solid husband shirt. Comfortable, clean-looking, easy to style, and definitely something he will actually wear.

Great Fit for Tall Men — Comfortable and Stylish
Size: 18.5" Neck 35"-36" Sleeve, Color: Cameo Blue
I bought the Van Heusen Men’s Tall FIT Dress Shirts in Poplin because it’s hard to find dress shirts that fit well for taller men. The fit is excellent — long enough in the sleeves and body, yet still tailored and comfortable. I especially like the blue color, which looks sharp and professional. I have already purchased multiple shirts and would definitely buy more. Very happy with these.
Key Features:
Tall fit designed for men with longer torsos and sleeves
Classic poplin fabric for a smooth, crisp look
Long sleeves with button cuffs
Traditional button-down front
Easy-care fabric, machine washable
Available in multiple colors for versatility
Modern, tailored fit that isn’t too loose
