Definitely like the athletic cut, Giving it 4 instead of 5 because it's just short enough that the shirt can come out at any movement let alone any unexpected movement. The collar was just a smidge to small. If purchasing go with the first number (18-18.5"). Initially I bought this as an experiment to see if I will buy more from Arrow. After, I went and purchased 4 shirts from another online retailer that I've dealt with before (different brand). I may try and get the next size up next time. But the big deterrent for me will be the length.
