Nice color, lightweight, but runs small
Color: Blue Gingham, Size: Large
Nice cookie and can be work tucked or untucked. The material isn’t best quality but it’s about as expected for a shirt this price range. The size runs small so buy a size up from what you normally do. Expect some shrinkage is well. Otherwise it’s a nice shirt!

Not the best fit
Color: Navy Gingham, Size: XX-Large
I like the design and color of the shirt. It runs small, I went up a whole size and the shoulder width is still a little tight. The fabric is also has small fibers all over it.

A large fits very well and I wear a 16.5" neck and a 34" sleeve. No shrinkage after many washings.
Color: Brown Gingham, Size: Large
This is my favorite shirt. It is very comfortable and great looking. I purchased the brown Gingham. I like wearing a black T-shirt under it. I wear a large and purchased a large. It is not too tight. With a dress shirt, I wear a 16.5 neck 34" sleeves. It will fit you if you wear a 35" sleeve, I believe. It is machine washable. I have washed it many time with no noticeable shrinkage. It has a shirt or pen pocket.
