Well, I'm lazy to take a photo of my suit so I take this pic from this forum (it's not my suit jacket, but the lapel of my suit jacket looks like this one). So. if I'm not correct in describing my suit looks like 3 roll 2 buttons, please forgive me and correct my mistake.
(The suit above is described as 2 buttons front)
Unless I'm missing something, this looks like a regular 2-button jacket to me. A 3-roll-2 would look similar, except that it would have a 3rd button on top right in the middle of the lapel roll. You would not button this button. Example: http://www.jpressonline.com/heritage-trim-fit-blazer-hopsacwool-3b/
