Just back from Rodeo- to me the 25 Rogue is similar to the LV speedy 25 in terms of size and capacity. The 25 seems like a good compromise since the larger Rogues tend to be heavy esp. with embellishments. If you can get beyond the need to carry a huge everyday bag, the 25 Rogue is quite adorable and practical as a crossbody. Love it! I am pretty sure I will get the black either with pink or the aubergine tea roses.
The dimensions are almost identical between the Speedy 25 and Rogue 25...different shape of course.
I have Speedy 25s but every time I see the Rogue I'm carrying something else and I think the Rogue is too small.
