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.
