I just pulled mine out to measure it. I have the 25 in Dark Turquoise with rivets and it is 9 3/4" across. I see yours is measuring almost a full inch less. I also noticed your white bag has white handles- which I've never seen before. The one on
Coach's site and dept. store sites has always had the oxblood handles.
I would suggest authenticating the Rogue in this thread here:

Follow the first post's directions on how to do it. Rogues are faked often, you want to make sure it's real.
