I have the black tea rose rogue 25. I've had since it first came out, and it is very structured, no slouching at all, not even on the bottom.
Hmm...I may bring it up to my SA then. I always feel guilty exchanging expensive bags for an issue that may be normal, but bothers me. For this price point, I need to be 100% satisfied. I'm playing around with all of my Rogues now and I don't think the leather on the tea rose is any thinner, it's just softer. Knowing that it'll softer with use, I'm afraid it'll really start slouching on the bottom.
