Update: I double checked the neck measurements after a request from a Styleforum member. All of them have a 15.5" neck, except for the Keaton cutaway collar, which is just over 15" (15.125").
If that one doesn't work for you due to the neck size, I could sell the other three together for $140 gifted. So for $40 less than the current Brooks Brothers deal, you get higher quality gear.
